Ruthenium Complexes with Coordinated Hydroxyiminoacetylacetonato or Bridging Nitrosyl Groups Formed by the Reactions of Nitrosylruthenium(III) with Acetylacetone

Abstract

Abstract Complexes formed by the reactions of nitrosylruthenium(III) with acetylacetone were investigated. The following products: [Ru(acac)2(hia)], 1; cis-[RuCl(NO)(acac)2], 2; and [Ru(NO)(acac)24], 3; (acac=C5H7O2− and hia=C5H6NO3−), were isolated as crystals and were characterized. On the basis of chemical and thermal analyses, and on the basis of observations of the magnetic properties, the conductivities, the molecular weights, the infrared spectra, and the NMR spectra, it was concluded that 1 contains the hydroxyiminoacetyl acetonato ligand, which is formed by the reaction of the coordinated nitrosyl group with acetylacetone, and that 2 contains a terminal nitrosyl group, and 3, bridging nitrosyl groups.
