Synthesis of 1,3-Diphenyl-4,5-bis(hydroxyimino)imidazolidine and Its Complexes with Nickel(II), Cobalt(II), Copper(II), Palladium(II), and Uranyl(VI)

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.
