Twelve dinuclear metal complexes of Co-II, Ni-II, Cu-II, Zn-II, Cd-II and H
g-II with two bis-bidentate azodye ligands have been synthesized. Both the
Co and Ni complexes are octahedral, the Cu complexes distorted octahedral a
nd the Zn, Cd and Hg complexes tetrahedral with both the ligands. All the c
omplexes are dimeric in nature.
