TEMPLATE SYNTHESIS OF TWO NEW GLYOXIME DERIVATIVES. CHARACTERIZATION AND INVESTIGATION OF THEIR COMPLEXES WITH Ni(II), Cu(II), AND Co(II) METAL IONS

Abstract

Two novel oximes containing di- and tetraoxime groups, dichloro-[N,N′-bis(2-aminophenyl)diaminoglyoxime]nickel(II), [Ni(LH₂)Cl₂], and {dichloro-[5,6:11,12-dibenzo-2,3,8,9-tetra-(hydroxyimino)-1,4,7,10-tetraazacyclododecane]}- nickel(II), [Ni(LH₄)Cl₂], have been synthesized by the template condensation reaction of dichloro-[N,N′-bis-(1,2-diaminobenzene)]nickel(II) with anti-dichloroglyoxime. Trinuclear complexes of [Ni(LH₂)Cl₂] with Ni(II), Cu(II) and Co(II) have been synthesized. A polynuclear complex of [Ni(LH₄)Cl₂] with Ni(II) has been prepared. The structures of these novel oxime compounds are proposed on the basis of the elemental analyses, IR and UV-Visible spectra and conductivity measurements. Conductivity measurements have shown that all complexes are non-electrolytes.
