Synthesis and Characterization of Heterocyclic Compounds

Abstract 1, 3-Dipheny1-4, 5-bis(hydroxyimino)imidazolidine (LH2) has been prepared from anti-dichloroglyoxime, N,N′-diphenylmethylenediamine, and sodium bicarbonate in ethanol. Complexes of Cu(II), Ni(II), Co(II), Pd(II), and UO2(VI) and LH2 give a metal-ligand ratio of 1:2. A tetrahedral complex is obtained for the Ni(II) complex by coordination through N and O atoms. The (LH2)Co. H2O complex is squarepyramidal while the Cu(II), Pd(II) and UO2(VI) complexes are square-planar. The structures of the ligand and complexes are proposed based on elemental analysis, mass spectral, 1H-n.m.r., i.r., u. v. -visible, and magnetic data.
