    THE SYNTHESIS AND NI(II), CO(II), CU(II), ZN(II), CD(II) AND UO2(VI) COMPLEXES OF N,N'-BIS(2-TOLYL)DIAMINOGLYOXIME AND N,N'-BIS(4-TOLYL)DIAMINOGLYOXIME

    N,N'-Bis(2-toyl)diaminoglyoxime (L(1)H(2)) and N,N'-bis(4-tolyl)diaminoglyoxime (L(2)H(2)) have been prepared from anti-dichloroglyoxime with o-toluidine and p-toluidine in ethanol. The complexes of these vic-dioximes with Ni(II), Co(II), Cu(II), Zn(II), Cd(II) and UO2(VI) metal ions have been investigated. The nickel(II), cobalt(ll) and copper(ll) complexes of the ligands have a metal-ligand ratio of 1:2 and the ligand oo-ordinates through the N atoms, as do most of the vic-dioximes. [Zn(LH)Cl(O-2)] and [Cd(LH)CI(H2O)] (LH(2) = L(1)H(2) or L(2)H(2)) form six-membered chelate rings and co-ordinate through N and O atoms. LH(2) reacts with UO2(CH3COO)(2) . 2H(2)O to give binuclear complexes with a metal-ligand ratio of 1:1. Their structures were identified by elemental analyses and H-1 NMR, IR, UV-visible spectroscopy, respectively.
