Abstract

AbstractA dioxime (LH2), [1,4-diaminobenzene-N, -bis(2-butylidine-3-one oxime], reacts with Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) to yield dinuclear complexes of general formula [M2(LH)2]Cl2 with a metal to ligand ratio of 2:2 with M = Co(II) or Cu(II), while Ni(II) forms complex [Ni2(LH)2(H2O)2Cl2] with a metal to ligand ratio of 2:2, whereas Zn(II) and Cd(II) form complexes of general formula [M2(LH)(H2O)2Cl2] with a metal to ligand ratio of 2 :1 . All complexes were characterized by metal content analyses, IR, electronic spectra, magnetic susceptibility and conductivity measurements. The Co(II) and Cu(II) complexes are proposed to be square planar while the Ni(II) complex is proposed to be octahedral and the complexes of Zn(II) and Cd(II) are tetrahedral.
