The reaction of [RuCl2(CO)3]2 with C5H5(SiMe3) has been re-investigated. In our hands, in refluxing tetrahydrofuran, the reaction gives consistently [Ru(CO)3(η-C5H5)][fac-RuCl3(CO)3], 1, and [RuCl(CO)2(η-C5H5)], 2, in 68 % and 12 % yield respectively. The reaction of CO with commercially available hydrated OsCl3 gives [OsCl2(CO)3]2 in 44 % yield. The crystal structure of [Ru(CO)3(η-C5H5)][fac-RuCl3(CO)3] is reported; superlattice symmetry is observed.
