The photochemical reaction of [Ru3(CO)12] with thioether ligands in THF leads to the isolation of tetranuclear ruthenium-carbonyl cluster compounds of the formula [Ru4(CO) 13(μ2-R2S)]. In these compounds, ruthenium atoms adopt a typical butterfly arrangement. If chelating ligands with two thioether functions are introduced, the reaction leads to mixtures of the trinuclear substitution products [Ru3(CO)10(RSSR)] and [Ru3(CO)8(RSSR)2]. The latter may be oxidatively cleaved by the use of chlorinated solvents to produce the mononuclear compound [Ru(CO)2Cl2(RSSR)] or the dinuclear complex [Ru2(CO)2(μ2-Cl)2Cl 2(RSSR)2] depending on the reaction conditions. Five new ruthenium-carbonyl-thioether complexes were characterized by X-ray diffraction. Irradiation of [Ru3(CO)12] in THF in the presence of thioether ligands yields ruthenium-carbonyl compounds [Ru4(CO) 13(μ2-R2S)] in the case of monodentate ligands, but [Ru3(CO)10(RSSR)] and [Ru3(CO) 8(RSSR)2] if bidentate thioether ligands are used. The latter may be oxidatively cleaved by CHCl3 to produce the dinuclear complex [Ru2(CO)2(μ2-Cl)2Cl 2(RSSR)2]. Copyright
