Synthesis of four new vic-dioximes and their nickel(II), cobalt(II), copper(II) and cadmium(II) complexes

Four unsymmetrical vic-dioximes: [L^sup 1^H^sub 2^] N-(4-butylphenyl)amino-amphi-glyoxime, [L^sup 2^H^sub 2^] N-(4-butylphenyl)amino-anti-glyoxime, [L^sup 3^H^sub 2^] N-(4-phenylazophenyl)amino-amphi-glyoxime and [L^sup 4^H^sub 2^] N-(4-phenylazophenyl)amino-anti-glyoxime have been prepared from amphi-chloroglyoxime, anti-chloroglyoxime, 4-butylaniline and 4-(phenylazo)aniline respectively. The complexes of these vic-dioximes with Ni^sup II^, Co^sup II^, Cu^sup II^ and Cd^sup II^ ions have been investigated. All are insoluble in common solvents. Their i.r. spectra and elemental analyses are given, together with mass and ^sup 1^H-n.m.r. spectra of the ligands.[PUBLICATION ABSTRACT]
