Synthesis of Ethane-1,2-bis(thioglyoxime) and Its Complexes with Nickel(II), Copper(II), Cobalt(III), Cadmium(II), and Uranyl(VI)

Abstract

Abstract A new tetra-oxime, ethane-1, 2-bis (thioglyoxime) (ETH4), has been prepared from 1,2-ethanedithiol and anti-chloroglyoxime. ETH4 has been polymerized by coordination with Ni(II), Cu(II), and Co(III). The Cd(II) complex is tetranuclear [(ET)Cl4(H2O)4Cd4] and the Zn(II) complex is binuclear [(ETH2)Cl2(H2O)2Zn2]. The uranyl complex is formed by coordination of O and S atoms of the ligand. Structures of the ligand and the complexes are proposed according to elemental analysis, magnetic measurements, 1H-n.m.r., i.r., and u.v.-visible spectral data.
