Controlled Molecular Magnetism of Bi- and Polynuclear Transition Metal Complexes Based on Hydrazones, Azomethines, and Their Analogs

Resumo

The possibilities of the magnetochemical method for the description of structures and properties of bi- and tetranuclear metallochelates and supramolecular architectures based on coordination compounds with restricted types of ligand systems, mainly hydrazones, azomethines, and their analogs, are reviewed. The known published data for the bi- and polynuclear complexes, whose paramagnetic centers are bound by both intra- and intermolecular exchange interactions, are systematized. A relationship between specific features of the electronic and geometric structures of the complexes and the character of the exchange effects is considered. Magnetostructural relations in the discussed compounds are systematized. The compounds discussed are important model objects for the development of the strategy for the targeted design of one-, two-, and three-dimensional magnetically ordered structures.
