SYNTHESIS OF A NEW GLYOXIME DERIVATIVE, CHARACTERIZATION AND INVESTIGATION OF ITS COMPLEXES WITH NI(II), CO(II), CU(II) AND UO₂(VI) METALS

Abstract

Abstract In this study, a novel dioxime having the 1,3-oxolane group, l,2-dihydroxyimino-3,7-di-aza-9,10-O-cyclohexylidene decane (H2L), has been synthesized from the reaction of l,2-O-cyclohexylidene-4-aza-7-amino heptane and anti-chloroglyoxime. Complexes of this ligand with Ni(II), Co(II), Cu(II) and UO2(VI) salts were prepared. The structure of the ligand and its complexes is proposed from the 1H and 13C-NMR, IR, mass spectral data, elemental analysis and magnetic susceptibility measurements. In addition, thermal properties of H2L and its complexes were also investigated by thermogravimetric analyses (TGA) and differential thermal analyses (DTA).
