Abstract

The reaction of bis(N-salicylidene)dicarboxylic acid dihydrazides (H4 Lig) with cobalt(II) salts was investigated. Chelates of the types Co(H3 Lig)X ·nH2O, Co2(H2 Lig)X 2, Co3(H3 Lig)2 X 4, Co(H2 Lig) ·nH2O and Co(H3 Lig)2 ·nH2O (X=Cl, Br, I or SCN) were isolated and characterized by their infrared and electronic spectra as well as their magnetic properties.
