Preparation and characterization of some metal complexes with heterocyclic azo ligand (4-SuBAI)‎

Abstract EN

The preparation and characterization of the Cu (II), Co(II), Ni(II), Zn(II), Cd(II), and Hg(II) metal complexes of heterocyclic azo ligand 2-[(4`-sulphamide phenyl) azo] -4,5-diphenyl imidazole (4-SuBAI) have been studied by elemental analysis, FT-IR and UV-Vis Spectroscopic, magnetic moment and molar conductance methods.

The analytical data showed that all chelate complexes were prepared with (metal-ligand) ratio of (1:2).

The general formula of these complexes was [ML2X2].

nH2O [were L=2-[(4`-sulphamide phenyl) azo]-4,5-diphenyl imidazole and X=Cl, and the octahedral geometry were suggested for these complexes .
