ABSTRACT:
The coupling reaction of 4-aminoazobenzen, 4-acetylaniline, and 4-methylaniline, after the diazotization reactions with 4,5-diphenylimidazole as coupling component in alkaline ethanolic solution were maintained to give three azo dyes (L1–3), namely, 2-[(p–Xphenyl)azo]-4,5-diphenylimidazole (X= C6H5–N=N–, CH3CO– and –CH3 for L1, L2 and L3, respectively). New mixed ligand complexes of these heterocyclic azo-ligands were prepared with Co(II), Ni(II) and Cu(II) transition metal salts and 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 imidazole and 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, and they are non-electrolytic in DMF.
