摘要：

Treatment of the unsaturated clusters [Os3(mu-H)(CO)8{mu-Ph2PCH2P(Ph)C6H4}] 1a and [Os3(mu-H)CO)8{mu-Ph2PC(=CH2) P(Ph)C6H4}] 1b with two-electron donor ligands gave the saturated clusters [Os3(mu-H)(CO)8{mu-Ph2PCH2P(Ph)C6H4}L] [L = CO 2a or PR3 or P(OR)3 3 (R = Me, Et, Pr(i), Bu or Ph)], [Os3(mu-H)(CO)8{mu-Ph2PC(=CH2)P(Ph)C6H4}L] (L = CO 2b) and [Os3(CO)8(dppm)L2] 4 [dppm = Ph2PCH2PPh2; L = CO, PR3 or P(OR)3]. Two different isomers of complex 4 are observed depending on the ligand L. All the products have been characterised by IR and NMR spectroscopy. The structures of [Os3H(CO)8{Ph2PCH2P(Ph)C6H4}(PPr(i)3)] 3a, [Os3(CO)8(dppm){P(OMe)3}2] 4a and [Os3(CO)8(dppm)(PPh3)2] 4c have also been established by X-ray crystallography.
