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. In this Volume, the Introduction Chapter has been thoroughly updated and recent trends in molecular magnetic materials with special reference to molecular nanomagnets and multifunctional magnetic materials as well as their theoretical aspects are summarized. The encouraging support of Michael Klinge, Sharon George, Antje Endemann and the whole production team from Springer is gratefully acknowledged. Jaipur March 2023

Introduction
General Remarks Polynuclear metal complexes have continued to attract considerable attention because of their outstanding physical properties and complexity of structures. Thus in continuation to our work on “Magnetic Susceptibility Data” starting with a new Volume II/31/A titled “Magnetic Properties of Paramagnetic Compounds” in 2012 [1] and four supplement volumes [2], herein we present more new volumes titled “Magnetic Properties of Paramagnetic Compounds – Magnetic Susceptibility Data” covering literature for the period 2001–2010. With increasing demand for online study material, a new pattern is being introduced to facilitate the search of magnetic data in online mode. During the decade of 2001–2010, studies are mainly focused on two types of molecular magnetic material – molecular nanomagnets and multifunctional magnetic materials [3, 4]. The area of molecular nanomagnets has largely involved work on single-molecule magnets (SMMs). Most SMMs are polynuclear clusters of different structural types. Many groups have reported the synthesis of such material by exploiting molecular (bottom-up) or classical (top-bottom) approaches [3, 5]. It is revealed that for SMM behaviour, it is not the size of the cluster but the value of the ground state-spin S and the magnetic anisotropy D that matters the most. Hence, a prerequisite for a useful SMM is that it should have a large ground-state spin, large negative D and small E according to the following Hamiltonian [4, 6, 7]: ℋ ¼ DS 2Z þ E S2x S2y where E ¼ energy of spin-levels The strength of the spin-orbit coupling is the main factor to determine the magnitude of anisotropy barrier rather than artificial optimization of D and S as suggested by Ruiz [8] and Peligkos [9] based on theoretical calculations.

Introduction
On the basis of above concepts, experimentally several groups have reported syntheses of SMMs of diverse structures [3, 4] but Mn12 complex, [Mn12O12(CH3COO)16(H2O)4].2CH3COOH.4H2O, first reported by Lis in 1980 [10] and its carboxylate derivatives remains one of the best choice that can function as SMM at the highest temperatures; others showing slow relaxation effects at lower temperatures. Next ferromagnetically coupled Mn19 aggregate has been reported that exhibited maximum spin ground state of 83/2, but it had very low anisotropy [6]. Another Mn10 cluster reported possessed rare T point group symmetry and high S ¼ 22 ground state spin [11]. The next break-through in the area of molecular nanomagnets was single-ion lanthanide SMM complexes [12]. Subsequently, Bogani [13] has reported a new rare-earth heteroleptic bis (phthalocyaninato)terbium(III) complex attached to single-walled carbon nanotubes (SWNTs) conjugate as promising unit in SMMs arena. The motivation for research in SMMs ranges from their application in magnetic storage of information, molecular electronics, quantum computing, magnetic drug delivery, contrast agents for MRI, etc [4]. Another related area which is fast-developing is that of single-chain magnets (SCMs) [14, 15] also called magnetic nanowires. Basically, these are one-dimensional equivalents of SMMs and have the properties of withstanding to higher temperature than SMMs for molecular paramagnets. One of the approach to design SCMs, illustrated by Miyasaka et al. [16], involved coupling of single-molecule magnets in one-direction. Later Tao [17] have argued that if SCMs could be crystallised into acentric or noncentric structures, it would be possible to obtain SCMs having nonlinear optical, ferroelastic and dielectric properties. Thus, this group has reported a novel MnIII 3 O complex which possessed, both magnetization relaxation and dielectric relaxation properties. Another noteworthy example is of vanadosilicate zeolite AM-6, first reported example of microporous material incorporating ferromagnetic chains [18]. Among magnetic nanoparticles, a new field of coordination nanoparticles (CNP) has also emerged during 2001–2010 decade particularly by Mann et al. [19] upon stability of nanocrystals of Prussian Blue Analogue (PBA). The light-induced magnetic behaviour was not examined until 2007 when Mallah [20] reported first example of photoinduced supermagnetism in trimetallic CNP, CuNiMo(CN)8. The field of organic molecule-based magnetic materials has also expanded rapidly and a library of about 40–50 ferromagnets have been well-documented [21]. Their ferromagnetic behaviour has also attracted widespread interest [22]. Among multifunctional magnetic materials, two categories of materials, viz switching magnetic materials and dual-function materials are being explored for advanced properties such as magnetic ordering combined with conductivity, superconductivity or ferroelectricity [3]. Examples of switching magnetic materials include spin-crossover compounds [23] and magnets based on PBA [24]. Dual-functional molecular materials displaying both conductive and magnetic properties are usually based on the use of charge-transfer salts [25]. A remarkable

example being cationic conducting network based on tetrathiofulvalene (TTF) and anionic metal complexes serving as magnetic components [26]. Next Robertson and co-workers [27] have reported ferromagnetism in a heavy atom heterocyclic resonance-stabilized bisdithiazolyl radicals conductor. Due to their promising applications in magnets, molecular switches and memory devices, interest in spin-crossover (SCO) systems has grown significantly, especially those of Fe(II) [28]. Some important examples are iron(II)-iron(III) mixed valence supramolecular pseudo-dimer [29], heptanuclear mixed-valence iron complex [30] and a 2D polymer {FeII(4-methylpyridine)2[AuI(CN)2]2 [31] in which an unprecedented three-step SCO behaviour has been observed. Despite powerful medical diagnostic applications of MRI, its low sensitivity has been a constraint [32–34]. To overcome the problems, multifunctional magnetic nanocrystals are emerging in biomedical applications as reported by Cheon et al. [35, 36]. Thus clinically, iron-oxide based magnetic nano-particles such as supermagnetic iron oxide (SPIO) and related systems have been widely explored for signal enhancing purposes. Focus has also been shifted to in vivo magnetic resonance detection of cancer cell lines by using water-soluble magnetic iron-oxide (WSIO) nanocrystals [33]. Besides gold nanoparticles, have also been exploited by cellular studies because of their hypothermal properties [34, 37]. Recently, a new class of MRI contrast agents based on chemical exchange-dependent saturation transfer (CEST) has attracted considerable attention because the image contrast can be switched “on and off” as per desirability by controlling parameters like pH, temperature, etc [38, 39]. It is reported that, of the lanthanide ions, ytterbium allows for the highest paraCEST effect. Thus, Burdinski [40] has synthesized Yb complexes of hexa-acetamide ligands and studied their CEST properties.
Susceptibility Units 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 cm3mol1. The SI units wherever reported have been changed into the cgs units by the following conversion factor: χM SI m3 mol1 ¼ 4π 106 χM cgs cm3 mol1 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.

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 has been being introduced with effect from volumes 1 to 4 – supplement to LB-II/31 series [2] 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.

Theoretical Aspects of Paramagnetic Susceptibility A detailed theoretical analysis of magnetic susceptibility has been described in the First Volume of II/31A Series [1]. Major new developments are summarized below: The susceptibility data for mixed-valent manganese-rods like SMM complex [Mn12O14(OH)2(C6H5COO)12 (thmne)4(C5H5N)2]{H3thme ¼ 1,1,1-tris(hydroxyme thyl)ethane)} with S ¼ 7 ground state were fitted to a model that assumed only the ground state to be populated [61].

where J ¼ MnIII-MnIII intradimer magnetic interaction DMn ¼ zero-field splitting parameter of a single MnIII ion Sz,Mn ¼ z component of the SMn operators On the basis of exchange interaction, slow relaxation of the magnetization at low temperature, M versus H data, hysteresis effects and finite-size effects, it is suggested that the magnetic properties of this complex could be regarded as intermediate between SMM and single-chain magnet (SCM). For single-chain magnet (SCM) (NEt)4[Mn2(5-MeOsalen)2Fe(CN)6] (5-MeOsalen2 ¼ N,N 0 -ethylenebis(5-methoxysalicylideneiminate) made of MnIIIFeIII-MnIII trinuclear SMM with an ST ¼ 9/2 spin ground state, magnetic susceptibility was calculated based on a Heinseberg trinuclear model with spin system (SMnSFe-SMn ¼ 2, ½, 2) and assuming JMn-Mn to be smaller than JMn-Fe and external magnetic field (H ) along the z axis (Hz) [16]: ℋ ¼ 2J MnFe ðS Mn1 S Fe þ S Mn1A SFe Þ þ gav μB STz H z

The magnetic susceptibility of oxalate (ox) based Fe(II) SCM [Fe(II)(ox) (btz)]n(btz ¼ benzotriazole) has been described by Keene, Price and Decurtins [63] and the data have been modelled from the equation of Drillion et al.

It is noted that the complex shows the Dzyaloshinskii-Moriya (D-M) interaction [65] which leads to spin canting through antisymmetric spin-exchange. A similar spin canting arising from D-M interaction [65] has also been observed in trimeric Co(II) magnetic coordination polymer, [Co3(OH)2(pa)2(ina)2] {pa ¼ 3-(1H-benzimidazol-2-yl)propanoic carboxylate; ina ¼ isonicotinate} [66].
