Abstract

In this study, transition metal complexes of Co(II) and Cu(II) with a newbisazo 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 and 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.

Key words: Tridentate, HMBC, HQSY, Transition,coloured complexes.
