Abstract
Abstract The reaction of dodecacarbonyltriruthenium (Ru3(CO)12) with tris(2-pyridylmethyl)ammonium perchlorate (tpa·3HClO4) in toluene, in the presence of acetic acid, produced a new ruthenium(II) complex of tpa [Ru(CH3CO2)(CO)(tpa)]ClO4·C6H5CH3 (1). A similar reaction of Ru3(CO)12 with 2-pyridylcarboxylic acid (pyCO2H) in toluene yielded a ruthenium(II) complex Ru(pyCO2)2(CO)2 (2). A related ruthenium(III) compound, [Ru(pyCO2)3]·H2O (3), was obtained from the reaction of RuCl3·nH2O and sodium 2-pyridinecarboxylate in a mixture of water and ethanol (1:1 by volume). The reaction of Ru3(CO)12, benzoic acid and pyridine (py) in toluene resulted in the formation of a dinuclear ruthenium(I) complex [Ru2(C6H5CO2)2(CO)4(py)2]·0.5C6H5CH3 (4). Compounds 1–4 have been characterized by IR, NMR and X-ray crystallography.
