Preface

In continuation to our efforts to update the magnetic susceptibility data of paramagnetic compounds, a new volume is presented herewith covering literature from 2001 to 2010. Since most of the researches these days consult the literature online, a new pattern has been introduced. All the magnetic properties of each individual substance are listed as a single document which is self-explainable and allowing search in respect of substance name, synonyms, common vocabulary, and even structure. It is hoped that the new pattern will facilitate greater accessibility of magnetic data and enhance the use of Landolt-Börnstein. The editor wishes to express her thanks to the authors R.T. Pardasani and Pushpa Pardasani for this excellent volume. The encouraging support of Michael Klinge, Sharon George, Antje Endemann and the whole production team from Springer is gratefully acknowledged. August 2020 New Delhi

Introduction

General Remarks With present four supplement Volumes, which compliment to and extend the “Magnetic Susceptibility Data” which was published as a new volume II/31A titled “Magnetic Properties of Paramagnetic Compounds” in 2012 [1]. A new pattern is being introduced to facilitate the search of magnetic data in online mode. The literature covered here shall be for the period 2001–2010. During this decade, within the field of magnetochemistry, there has been continuing and growing interest in the design and characterisation of polymeric materials. The 1D, 2D or 3D new materials have been formed through various bridging ligands such as azido [2a], pyrazine [2b], bipyridines [2b], nitrosyl nitroxide [2c, 2d], etc. Single-molecule magnetic materials have also been reported and their low-temperature magnetic behaviour studied [3]. Many studies on ion-pair complexes (donor-acceptor system) have also been conducted since the discovery of metamagnetism in such compounds [4a, 4b]. Spin-crossover phenomenon also continues to be an attractive area of study [5a, 5b]. Perhaps the most striking feature has been the application of gadolium(III) complexes as a contrast enhancing agent for MRI [6]. In addition, these compounds have also stimulated theoretical investigations. The susceptibility data have again been mostly reported at room temperature and the studies down to 0.0 K have oftenly been reported in the form of figures (as curves of χ M vs. T or μeff vs. T or χ MT vs. T). Throughout the volume the data have been reported in CGS units, commonly abbreviated as cgs or cgs-emu and represented as cm3 mol
1. The SI units wherever reported have been changed into the cgs units by the following conversion factor:


 χ M SI m3 mol
1 ¼ 4π  10
6 χ M cgs cm3 mol
1 The sign convention used throughout this volume is that negative value of J signifies antiferromagnetic coupling i.e. where the ground state has minimum multiplicity. All over the files ‘c’ after numbers stands for corrected value of magnetic moment and paramagnetic susceptibility after making diamagnetic corrections. © Springer-Verlag GmbH Germany, part of Springer Nature 2021 A.

Introduction

Organization of Files With the objective to collate the enormous amount of information on magnetic susceptibility parameters of a very large number of a variety of skeletons and present it in a form that can readily be retrieved and used, a new pattern is being introduced with volumes II/31B–I keeping in view that now a majority of research groups look at the scientific data electronically. All the magnetic properties of each individual substance are being documented as a single file and every single document is self-explainable. Each file is comprised of Title of the document listing searchable and common vocabulary as well as synonyms, Name of the substance according to IUPAC system and its abbreviated formula, CAS-number (wherever available), Gross formula, Properties – listing all properties reported using a standard SpringerMaterials term (see next section) and the Structure – a completely drawn structure of the molecule and/or ligand as well as a separate molefile of the compound is provided to allow even structure searches. The magnetic data have been presented in the form of table. It is followed by additional remarks such as susceptibility equations, exchange parameters, etc. and figures with captions showing curves of χ M vs. T or μeff vs. T or χ MT vs. T, wherever appropriate. Temperature and pH dependence, if reported, is indicated in the remarks column. As far as possible the reference is made to the original literature. The files are listed under their central metal ion or atom (transition metal, lanthanide or actinide). The transition elements are listed by the group in which they occur in the periodic table starting with Group IV (Ti, Zr, Hf) and proceeding until Group I (Cu, Ag, Au) followed by lanthanides and actinides. (Cu and lanthanides and actinides are published in volume II/31C.)

Ref. [7] [8] [9–12] [13–17] [18, 19] [20] [21] [22] [23, 24] [25, 26]

Their general description is given in the standard books [27–29]. With the aim to remove confusion and ambiguity concerning various previously reported magnetic parameters for commonly used magnetic susceptibility calibrant HgCo(NCS)4 Nelson and ter Haar [30] have measured for the first time single-crystal magnetic susceptibility data for HgCo(NCS)4 on SQUID magnetometer. The measurements have been carried out in the temperature range 1.7–300 K and utilized in conjection with powder data; also collected for the first time on a single magnetometer and throughout the tewmperature range 1.7–300 K. It is demonstrated that temperatureindependent paramgnetism, zero-field splitting, and magnetic exchange are all required in order to account for the observed magnetic behavior.

Theoretical Aspects of Paramagnetic Susceptibility Magnets have fascinated mankind since the discovery of iron metal by Hittites some 3500 years ago. The compounds that exhibit magnetism are inorganic solids and molecule-based organic materials. The number of different magnetic behaviours that can be observed in a solid is fairly large and indeed the tree of magnetism can be divided into many branches. Nevertheless, six classes are of particular importance, namely diamagnetism, paramagnetism, ferromagnetism, antiferromagnetism, ferrimagnetism, and metamagnetism (see Fig. 1) [31]. The origin of paramagnetism is the spin and orbital angular momentum possessed by extra-nuclear electrons. All substances when placed in a magnetic field of strength H exhibit magnetic moment M given by M ¼ χH, where χ, the proportionality constant, is the magnetic susceptibility [28, 29, 32]. In open-shell paramagnetic compounds the induced moment is aligned parallel to the field and susceptibility may be expressed by the equation:

For non-interacting independent spins the susceptibility is inversely proportional to the temperature and is given by Curie law: χM ¼

ð3Þ

where N is Avogadro’s number, g is the Lande factor (the ratio of magnetic moment to angular momentum), μB is the Bohr magneton, k is the Boltzmann constant, J ¼ total angular momentum ¼ S + L, x ¼ gJμBB/kT, and C is the Curie constant per mole. The Curie law is followed by many magnetically dilute substances. However, a secondorder contribution to paramagnetic susceptibility, the temperature-independent paramagnetism (TIP), Nα, should also be taken into consideration. Thus closed-shell diamagnetic compounds have their induced moments aligned antiparallel to the field and possess a temperature-independent negative susceptibility. Hence the molar susceptibility corrected for the diamagnetism may be given by the equation: χ corr M ¼

Nμ2eff þ Nα 3kT

However, a large number of data have been reported in terms of temperatureindependent effective magnetic moment term:

S is the resultant spin quantum number. For substances which are not magnetically dilute, the temperature dependence of susceptibility is often expressed by the Curie-Weiss law: χM ¼

Nμ2 C ¼  eff  T

ð6Þ

The constant Θp is known as paramagnetic Curie temperature or Weiss constant and is readily obtained by plotting 1/χ M against T. For free ions, two limiting cases exist. If the multiplet separation hν is large compared to kT, only the lowest energy level is populated and the effective magnetic moment is given by: μeff ¼ g

On the other hand, if hν is small compared to kT, all multiplet levels are equally populated and μeff ¼

where L and J are total orbital and angular quantum momentum, respectively. This is the general equation for transition metal ions. When the ground states of transition metal ions are S states, L ¼ 0, there will be orbital quenching and μeff ¼

Unlike transition metal ions the magnetic moments of lanthanide ions (Ln3+) are not effected by the ligand field. The 4f electrons are so well screened that they are least effected by external influences. At sufficiently low temperature the spins may order. The last four types of magnetic behaviours are thus characterized by the cooperative behavior of the spins. In ferromagnetism, the individual spins can be either all identical or different from each other but the coupling is such that they are all parallel to each other in the ordered face (Fig. 2a). Then a spontaneous magnetization at zero applied field occurs with characteristic saturation moment Ms in a finite applied field and can be calculated by Eq. (10): Ms ¼ NgSμB

ð10Þ

In both antiferromagnetism and ferrimagnetism there are at least two kinds of different spins that are coupled antiparallel to each other. When the two different spins have identical moments, the magnetization of the two sublattices cancel, and antiferromagnetism results (Fig. 2b). There is no net moment in zero applied field

and the susceptibility is anisotropic below the Néel temperature. On the contrary, ferrimagnetism occurs when the antiferromagnetically aligned spins have differing local moments resulting in incomplete cancellation of the parallel and antiparallel spin sublattices leading to reduced, but non-zero, moment (Fig. 2c). The saturation magnetization for a ferrimagnet may be calculated from Eq. (11) or (12) depending if complete cancellation of sublattices magnetic moments arises from differences in g or S, respectively [33]. Ms ¼ N ΔgSμB

With respect to the magnetic susceptibility of an antiferromagnet two situations can arise: (i) The applied magnetic field is perpendicular to the axis of the spin χ⊥ ¼

and the magnetic susceptibility is thus independent of the field. (ii) The applied magnetic field is parallel to the axis of the spin χk ¼

And hence at T ¼ 0 K, χ || ¼ 0, and at T ¼ TN (or ΘN), χ || ¼ χ ⊥, where TN ¼ Néel temperature Application of a magnetic field to a ferromganet leads to alignment of the ferromagnetic domains and M(H ) exhibits hysteresis behavior. Metamagnetism is the field dependent transformation from an antiferromagnetic state to a high moment ferromagnetic state. In order to describe interaction between two spins S1 and S2, it is customary to refer to a coupling constant defined by the spin Hamiltonian, H ¼ J ðS1  S2 Þ where J is the energy separation between a singlet and a triplet [28, 32]. The centers characterized by the spins S1 and S2 may interact with each other through a weak binding interaction. If the orbitals containing the unpaired electron(s) in the two centres are orthogonal to each other, then Hund’s rule keeps the spins parallel to each other and the parallel coupling between the two arises while if they have non-zero overlap, antiparallel alignment is favoured. The two spin centres may be also well separated from each other provided that intervening spin paired centres can transmit interaction through different superexchange mechanisms. The molar susceptibilities of the antiferromagnetically coupled dn–dm dimers are calculated by using Van Vleck equation [34]: χM ¼

Theoretical Aspects of Paramagnetic Susceptibility

For the derivation of the magnetic susceptibility equation for the homometallic tetranuclear system, three exchange integrals should be taken into consideration, J, J 0 , J 00 . Based on the Heisenberg model and by the use of Van Vleck equation [45] and assuming that one or two of the exchange integral is negligibly small, the magnetic susceptibility equation per metal for the tetranuclear system is given by: χA ¼

4J=kT Þ þ 2 exp ð

For high-nuclearity clusters, the complexity of the system leaves an uncertainty in the interpretation of the magnetic data, illustrating an inherent weakness in the capability of the theoretical methods to deal with such systems. For mixed-valence compounds magnetic behavior has been analysed from the perspective of the Kambe model [46] for trimers exhibiting isotropic exchange (J12 ¼ J13 ¼ J23 ¼ J ) (Eq. 30) or anisotropic exchange (J12 ¼ J13 ¼ J, J23 ¼ J 0 ) (Eq. 31) [47]: χM ¼ χM ¼

However, in case of MnII-MnIII mixed oxidation state clusters, a general spin-spin interaction model allowing for dissimilar coupling between MnII-MnIII pairs could not be constructed by using Kambe method for isotropic spin Hamiltonian and a detailed analysis is discussed by Hendrickson and co-workers [48, 49] for [Mn6O2(O2CPh)10(Py)2(MeCN)2]  2MeCN and [Mn9O4(O2CPh)8(sal)4(salH)2(Py)4] clusters. For a linear chain polymer like [Cu(dien)(OAc)]n(ClO4)n] [50] magnetic properties could be explained by Heisenberg linear-chain model Hamiltonian: H ex ¼

where J is the interchain-exchange coupling constant and the summation is over all members of the chain based on Baker et al. model [51], the equation for a S ¼ ½ ferromagnetic chain is:

where K ¼ J/2kT, and ai and bi are expansion coefficients. Taking into account the interchain exchange by addition of a mean field correlation term, the susceptibility can then be calculated from the equation: χ¼

J 0 is the interchain-exchange coupling energy and z is the number of nearest neighbours. For most of the trivalent rare earth ions the 2S+1LJ free-ion ground state is well separated in energy from the excited state such that only this ground state is thermally populated at room temperature and below [52]. In the free-ion approximation the molar magnetic susceptibility for a mononuclear species is then given by χ ðJ Þ ¼
