Self-Assembly in the Systems MX2–Nicotinic Hydrazide–Pyruvic Acid (М = Со, Ni; X = Cl, CH3COO)

Abstract

In the course of self-assembly in the systems MX2–nicotinic hydrazide (HN)–pyruvic acid, where М = Co, Ni; X = Сl, CH3COO, complexes of composition: [CoCl(HNРv)(H2O)2], [Co(HNРv)2], [Ni(HIРv)2] have been synthesized. Local atomic structure of the coordination centers was established by the method of X-ray absorption spectroscopy. Thermal stability, electric conductivity, and magnetic susceptibility of the complexes have been determined.
