Synthesis and Characterization of Some Metal Complexes of Cystine: [Mn(C_6H_(10)N_2O_4S_2)]; where M~(II) = Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Hg(II) and Pb(II)

摘要

Cystine forms metal complexes of general formula [M~(II)(C_6H_(10)N_2O_4S_2)]; 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 NaHCO_3 solution. The complexes were formulated by comparing the C, H, N, S and metal analysis data. The prepared complexes were characterized by different phys-icochemical 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.
