Self-assembling in the systems МХ2–2-(7-bromo-2-oxo-5-phenyl-2,3-dihydro-1Н-1,4-benzdiazepin-1-yl)acetohydrazide–salicyl aldehyde (М = Сo, Ni, Zn; X = Cl, CH3COO)

Abstract

By self-assembling in the systems MX2–2-(7-bromo-2-oxo-5-phenyl-2,3-dehydro-1Н-1,4-benzdiazepin-1-yl)acetohydrazide (Hydr)–salicyl aldehyde (HSal) (М = Co, Ni, Zn; X = Cl, CH3COO) the complexes of composition [Co(HydrSal)2], [Ni(HydrSal)2], [Zn(HydrHSal)Cl2], [Zn(HydrSal)(CH3COO)(H2O)] have been synthesized. The local atomic structure of the coordination unit was determined by the method of X-ray absorption spectroscopy. Thermal stability, electroconductivity, and magnetic susceptibility of the complexes have been studied.
