Abstract: This paper involved, The coupling reaction of 4-methoxyaniline, 4-acetylaniline, 4-nitroaniline, and 4-methylaniline, after the diazotization reactions with 4,5-diphenylimidazole as coupling component in alkaline ethanolic solution were maintained to give four azo dyes (L1–4), namely, 2-[(p–Xphenyl)azo]-4,5-diphenylimidazole (X= CH3O–, CH3CO–, –NO2 and–CH3 for L1, L2, L3, and L4, respectively) and its characterized study after precipitation and re-crystallized use available an analytical spectroscopic, including F.T.I.R , UV-Vis spectrophotometer , C.H.N for the elements,also mass spectrometry and thermal analysis of the two samples of azo ligand. New mixed ligand complexes of these heterocyclic azo-ligands were prepared with Cu(II) transition metal salt. A series of a new copper(II) complexes [Cu(L1 or L2 or L3 or L4)(PPh3)2(N3)2] (1a–4a) their characterized by available techniques such as elemental analysis, determination of metal content M% , molar conductances, magnetic moment measurements, IR and UV–Vis spectral studies. The arylazo-4,5-diphenyl-imidazole dyes acts as a neutral bidentate ligands, coordinating through(N3) nitrogen atom of imidazoleand the other nitrogen atom of azo group which is the farthest of heterocyclic molecule to form five member metalo-cyclic ring . The analytical and spectral data showed that the complexes have octahedral geometry, andthey are non-electrolytic in DMSO.
