The structures and dynamic magnetic behaviours of 31-Dy4 and 31-Tb4 have been presented in Figure 3.22. Four lanthanide ions are aggregated in the grid-like metal core by a central p4-S and eight peripheral i2-S atoms from ethanethiol ligands [38]. The individual lanthanide centres occupy distorted six-coordinate [LnNS5] octahedral coordination environments. Ac susceptibilities measurements reveal pronounced temperature dependence with a series of maxima below 28 K, typical for SMM behaviour, in complex 31-Dy4. Furthermore, an... 

In the first case, ID materials exhibit a peculiar magnetic behaviour only in a restricted class of compounds comprising nitronyl-nitroxide radicals. Much richer is the literature on anisotropic 4f ions showing slow relaxation of the magnetization due to SCM behaviour. 

The wave functions of the ground and excited states of lanthanides have a truly multiconfigurational character.1 Therefore, computational description of both the ground state and the low-lying excited states, which are important for magnetic behaviour, is only possible by a multiconfigurational ab initio method. In this respect, the C ASSCF method proved to be a reliable tool for the description of electronic properties of lanthanide complexes.
