The reaction of [Cp-2(*)Ru-2(CO)(4)] [a: Cp(*) = Cp* (eta(5)-C5Me5); b: Cp(*) = Cp-x (eta(5)-C5Me4Et)] with beta-real-gar in boiling n-decane gives [Cp-2(*)Ru2As4S4] (1 a,b) in good yields along with some [Cp-2(*)Ru2As4S2] (2 a,b). According to X-ray diffraction analyses of 1b and 2a, their structures belong to two different types of inorganic clusters. Whereas 1b has a cage structure in which the Cp-2(*)Ru-2 unit is inserted into the As4S4 cradle, 2a has a sandwich structure in which two coplanar eta(2)-As2S ligands and the Cp* ligands are oriented parallel to one another. Analysis of the As-S connectivity in the core of 1b reveals a structural relationship to the extremely rare form of arsenic sulfide As4S4(II), and not to the metastable high-temperature form beta-As4S4 used in the synthesis. At lower temperatures (60, 115 degrees C) formation of CO-containing products is observed.
