Synthesis And Spectrophotometer Study 2-[(2-Sulfopheny)Azo]-4,5-Diphenylimidazole With Some Transition Metal Complexes
Abstract
This study is concerned the synthesis of Co(III), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II) complex of 2-[2-sulfophenyl) azo] -4,5- diphenyl imidazole (SAI). Complexes has been studied, such as, molar concentration, effect of time on a formation of the complexes and pH values. The expected structure of these complexes were by mole Ratio method, the results showed that all of these complexes have a mole ratio (1:2) (metal: reagent) except Cu+2 which have amole ratio (1:1) and melting points measurement of these complexes showed high stability. IR and UV-Vis spectra of free reagent showed some changes comparing with high reagent changes comparing the spectra of complexes.
