The title compound, [Os(3)(C(6)H(12)N(3)P)(4)(CO)(8)], crystallizes in the ortho­rhom­bic space group Pbca with Z = 8. The mol­ecule consists of a triangular triosmium(0) core surrounded by eight carbonyl ligands and four 1,3,5-tri­aza-7-phosphatri­cyclo­[3.3.1.1(3,7)]decane (or PTA) ligands. One Os...

Descripción
Sumario:The title compound, [Os(3)(C(6)H(12)N(3)P)(4)(CO)(8)], crystallizes in the ortho­rhom­bic space group Pbca with Z = 8. The mol­ecule consists of a triangular triosmium(0) core surrounded by eight carbonyl ligands and four 1,3,5-tri­aza-7-phosphatri­cyclo­[3.3.1.1(3,7)]decane (or PTA) ligands. One Os atom is coordinated by two PTA ligands and two CO ligands, while the other two Os atoms are each bonded to a single PTA ligand and three CO ligands. There is a small disorder associated with the Os(3) unit so that a minor orientation has an occupancy of 2.17 (4)%. The title compound represents the first structurally characterized triangular Os(3) carbonyl cluster with four monodentate tertiary phosphane ligands. [Image: see text]
