Coordination Compounds of CoII, NiII, CuII, ZnII, CdII and HgII with Tridentate ONS Donor Azo dye Ligands

Twelve monomeric co–ordination compounds of CoII, NiII, CuII, ZnII, CdII and HgII with two ONS tridentate azodye ligands have been synthesized. The characterizations of these compounds have been made basing upon analytical conductance, magnetic susceptibility, I.R, electronic spectra, E.S.R. and N.M.R. spectral data. The CoII and NiII complexes are found to be octahedral, CuII complexes are distorted octahedral and ZnII, CdII and HgII complexes are found to be four co-ordinated possibly with tetrahedral geometry.
