Cystine forms metal complexes of general formula [M-II(C6H10N2O4S2)]; where M-II = Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Hg(II), and Pb(II) in the aqueous medium. Before reacting with metal salts the ligand solution was neutralized by NaHCO3 solution. The complexes were formulated by comparing the C, H, N, S and metal analysis data. The prepared complexes were characterized by different physicochemical methods. The UV-vis, FTIR spectral analysis, magnetic susceptibility of these complexes are discussed. Cyclic voltammetric studies of some of the complexes are also reported.
