Abstract
The compounds Ru3(CO)9(SnPh3)2(NCMe)(μ-H)2 (1), Ru3(CO)10(SnPh3)2(μ-H)2 (2), Ru(CO)4(SnPh3)2 (3) and Ru(CO)4(SnPh3)(H) (4) were obtained from the reaction of Ru3(CO)10(NCMe)2 with HSnPh3 in hexane solvent. Compounds 1, 3 and the new compound Ru3(CO)7(SnPh3)3(NCMe)2(μ-H)3 (5) were obtained from reaction of Ru3(CO)10(NCMe)2 with HSnPh3 in a CH2Cl2 and MeCN solvent mixture. 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) which contain bridging SnPh2 ligands. Compound 7 was found to react with Pt (PBu3t)2 to yield the bis-Pt (PBu3t) adduct, Pt2 Ru3 (CO)10 (PBu3t)2 (μ3 - SnPh2)2 (9) in 59% yield by the addition of Pt (PBu3t) groups to two of the Ru-Sn bonds to the bridging SnPh2 ligands. Fenske-Hall molecular orbital calculations were performed to provide an understanding of the metal-metal bonding in the clusters of 7 and 9. Compounds 1, 2, 5, 6, 7 and 9 were characterized structurally by single crystal X-ray diffraction analysis.
