Kurzfassung englisch:
Despite of the existence of rare predictive models, e.g. for 1D chain type triazole-based Fe(II) coordination polymers [1], it is still impossible to predict the spin transition behaviour of almost any new spin-crossover (SCO) compound. But within a series of homologue ligands a systematic variation may elucidate the impact of steric and/or electronic factors upon the spin transition properties such as the spin transition temperature T½ and the abruptness of the transition. A comparative study on the impact of the spacer chain length within the class of alpha,omega-ditetrazolyl-alkanes shows dramatic changes from a rather flexible 1D chain-type [2] to a more rigid 1D chain-type [3] and a very rigid 3D threefold interpenetrated [4] coordination polymer (Fig. 1) and its consequences for the spin crossover behaviour. Furthermore, the peculiarities of the SCO behaviour of mononuclear Fe(II) complexes with series of halo-substituted alkyl-tetrazole ligands will be presented.
