Synthesis and Characterization of Co(II) and Cu(II) Complexes of a new bisazo dye derived from 4,5-diphenyl imidazole

In this study., Transition metal complexes of Co(II) and Cu(II) with a new bisazo dye (2-(4-methoxy-2-(4-methoxy phenyl)diazenyl)phenyl)diazenyl)-4,5-diphenylimidazole were synthesized and characterized by elemental analysis, electronic data, FT-IR, 1H-NMR, 13C-NMR, HMBC, HQSY, molar conductivity measurements. It has been found that the bisazo ligand behaves as tridentate (N,N’,N") donor ligand forming chelates with (1:2) (metal: ligand) stoichiometry.
