Abstract
Derivatives of acetylacetonato-nickel(II) in which the coordinating oxygen is replaced by sulfur to various extents have been isolated by the reaction between nickel(II) acetylacetonate and hydrogen sulfide in an ethanolic solution, using hydrogen chloride as the catalyst. These compounds are soluble in organic solvents, such as benzene, acetone, or carbon tetrachloride, but can hardly be dissolved in water. The proton magnetic resonance spectra indicate that the proton of the methyl group attached to the C=S carbon gives greater chemical shifts than that of the methyl group attached to the C=O carbon. The infrared spectra of these compounds are discussed with particular reference to the C=S stretching bands. The electronic spectra of these compounds and the Hückel LCAO-MO calculation of bis dithio compounds are also compared.Keywords
