Coordination compound magnetic properties

The dinuclear asymmetric [Gd2(Tp)2(DTBSQ)4]CHCl3 consists of two Gd ions, one eight- and the other nine-coordinate. The magnetic properties of this compound have been investigated by magnetic susceptibility measurements and high-field electron param-agnetic resonance spectroscopy.

Pauling further extended the sp"dm hybridization approach to the d-block compounds.3 By varying the relative importance of p and d orbitals, Pauling was able to construct hybrid orbitals that rationalized the geometries and magnetic properties of many transition-metal coordination complexes. For example, the square-planar... 

Aromaticity remains a concept of central importance in chemistry. It is very useful to rationalize important aspects of many chemical compounds such as the structure, stability, spectroscopy, magnetic properties, and last but not the least, their chemical reactivity. In this chapter, we have discussed just a few examples in which the presence of chemical structures (reactants, intermediates, and products) and TSs with aromatic or antiaromatic properties along the reaction coordinate have a profound effect on the reaction. It is clear that many more exciting insights in this area, especially from the newly developed aromatic inorganic clusters, can be expected in the near future from both experimental and theoretical investigations.

In an early publication, Zelentsov reported the preparation of a complex with subnormal magnetic properties 44 = 0.87 BM) with the SB (101).777 The compound was prepared from dibenzoylmethane and o-aminophenol. The V02+ complex with (102) has also been shown to be involved in antiferromagnetic exchange with J = —139 cm-1. Revenko and Gerbeleu prepared several V02+ complexes of (103) derived from Hsal and thiosemicarbazide which were reported to involve ONS coordination.778 The measured were 1.27, 1.21 and 1.33 BM for R = H, Cl and Br, respectively. The complexes are not anhydrous and a dimeric structure (104) was proposed.
