A new vicinal dioxime ligand (1E,2E)-N 1,N 2-bis(2-formylphenyl)-N c1,Nc2-dihydroxy - ethanediimidamide (H2L) has been synthesized by the rea tion of o-anisidine with dichloroglyoxime. Mononuclear complexes with some transition metal ions have been prepared. This compound forms square-planar metal complexes (M(HL)2), with Ni(II), Co(II) and Cu(II), with a metal ligand ratio of 1:2. Also, the tetrahedral complexes of Hg(II), Cd(II) and Zn(II) have been prepared and were found to have a metal ligand ratio of 1:1. The results indicated that the metal ions are coordinated through two N atoms of the ligand, as do most of the vic-dioximes. H2L forms the binuclear nonplanar N, O co or - dinating complex [(H2L)(OH)2M2] and a metal ligand ratio of 1:1 with M = U(VI)O2. The composition and structural formula of these complexes were confirmed by elemental analysis, IR, MS, and NMR spectroscopic methods.
