Abstract
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 .
Highlights
Azo imidazole derivatives are very important class of chemical compounds receiving attention scientific research[1]
The present study reports the preparation and spectral characterizeation of new azo imidazole ligand (4SuBAI) and some of its metal complexes
The hetero cyclic azo ligand was prepared according to the general method [13] by dissolving (4.03gm, 0.01 mol) of sulfanilamide in 2ml of concentrated hydrochloric acid, 10ml ethanol and 10ml distilled water
Summary
Azo imidazole derivatives are very important class of chemical compounds receiving attention scientific research[1] They are highly colored and have been used as dyes and pigments for along time.[2,3]. The hetero cyclic azo ligand was prepared according to the general method [13] by dissolving (4.03gm, 0.01 mol) of sulfanilamide in 2ml of concentrated hydrochloric acid, 10ml ethanol and 10ml distilled water. To this mixture a solution of 10% of sodium nitrate in dissolved distilled water was added dropwise at (0-5) oC and left to stand 15min. The yield was 75% of dark orange crystals the procedure was seen in scheme
