Ambidentate coordination of the oxime group in 1-ethoxycarbonyl-2-alkylimino-propanone oximato)(1-ethoxy-(carbonyl-2-imino-1-propane oximato)nickel(II) complexes

Abstract

Mixed ligand complexes, of the formula (1-ethoxycarbonyl-2-alkylimino-1-propanone oximato)(1-ethoxycarbonyl-2-imino-1-propanone oximato)Ni^||, Ni(R-IEI)(IEI'), where R=CH₃, C₂H₅, n-C₃H₇ n-C₄H₉ or C₂H₄OH, have been prepared. The electrical conductance in acetone shows the non-electrolytic nature of the complexes while the cryoscopic molecular weight determination in benzene indicates their monomeric nature. The diamagnetic character shows square-planar stereochemistry for these complexes. The ir and nmr spectra suggest the coordination of the isonitroso group of R-IEI through nitrogen and that of IEI' through the oxygen.
