Reactions of Nickel(II), Copper(II) and Palladium(II) Complexes of Bis(acetylacetone)ethylenediimine with Nitric Oxide

Abstract

Abstract Through reaction with nitric oxide, divalent Ni, Cu, and Pd complexes of bis(acetylacetone)-ethylenediimine have been shown to yield fine crystalline compounds of the general formula M(C12H17N3O3), where M=Ni or Cu, and of M(C12H16N4O4) where M=Ni, Cu or Pd, depending on experimental conditions. They are insoluble in water. The former compounds are rather soluble in common organic solvents, but the latter are sparingly soluble, except in pyridine. On the basis of analytical data and IR-spectral analyses, they are thought not to be nitrosyl metalcomplexes but oxime type complexes.
