Six tetrameric and six dimeric complexes of CoII, Ni II, CuII, ZnII, CdII and Hg II with one hexadentate (bistridentate) O∩O ∩N-N∩O∩O donor and one tetradentate (bis-bidentate) O∩N-N∩O donor azo dye ligands, 4,4′-bis(2′-hydroxy-3′-carboxy-5′-chlorophenylazo)-3, 3′-dimethoxydiphenyl [LH4] and 4,4′-bis(2′- hydroxynaphthyIazo)-3,3′-dimethoxydiphenyl [L′H2] have been synthesized and characterized by analytical, conductance, magnetic susceptibility, IR, electronic spectra, ESR, NMR and X-ray diffraction (powder pattern) data. The cobalt(II) and nickel(II) complexes are octahedral, copper(II) complexes are distorted-octahedral and a tetrahedral stereochemistry has been suggested to zinc(II), cadmium(II) and mercury(II) complexes.
