Ruthenium-tin complexes from the reaction of HSnPh3 with Ru3(CO)10(NCMe)2 and their reactions with bis(tri-t-butylphosphine)platinum

Three new triruthenium compounds: Ru3(CO)9(SnPh3)2(NCMe)(μ-H)2 (1), Ru3(CO)10(SnPh3)2(μ-H)2 (2) and Ru3(CO)7(SnPh3)3(NCMe)2(μ-H)3 (5) were obtained by multiple oxidative additions of HSnPh3 to Ru3(CO)10(NCMe)2. Compound 2 and the new compound Ru3(CO)9(SnPh3)3(μ-H)3 (6) were obtained from reactions of 1 and 5 with CO, respectively. Compounds 2 and 6 eliminated benzene when heated to yield Ru3(CO)10(μ-SnPh2)2 (7) and Ru3(CO)9(μ-SnPh2)3 (8). Compound 7 reacted with Pt(PBu3t)2 to yield Pt2Ru3(CO)10(PBu3t)2(μ3-SnPh2)2 (9).
