Spectral features and structure of zinc and cadmium coordination compounds with carboxylic acid hydrazides

Complex compounds of Zn and Cd nitrates and perchlorates with tetrazonyl-1-acethydrazidan (TH-1) were synthesized and investigated by the method of IR-spectroscopy. X-ray diffraction analysis of [Cd(TH-1)2](ClO4)2 compound was conducted. Insufficient shift of band of valence vibrations of ligand carbonyl group, which takes place during coordination, was observed in IR spectrum of the compound. It was established that TH-1 played the role of tridentate chelate-bridge ligand and entered the coordination sphere of one Cd atom by nitrogen atom of hydrazine group and carbonyl oxygen atom
