Synthesis of the (μ-H)Os3(μ-NH2)(CO)10 cluster is described. The reactivities of this compound and the (μ-H)Os3(μ-OH)(CO)10 cluster toward some bases (PPh3, Py) and trifluoroacetic acid are compared with one another. The structure of the (μ-H)Os3(μ-NH2)(PPh3)(CO)9 complex is established by X-ray diffraction analysis. The compound crystallizes in the orthorhombic system: a = 22.447(9) Å, b = 14.831 (8) Å, c = 9.222(4) Å, V= 3070(3) Å3, space group Pna21, Z=4, ρcalcd = 2.384 g/cm3 for empirical formula C27H18NO9Os3P1,R F = 0.0266. The three Os atoms form a nearly regular isosceles triangle. The terminal phosphine ligand lies in the plane of the metallocycle and is trans to the Os(1)-Os(3) bond. The bridging NH2 ligand is positioned over the plane of the Os3 triangle. The angle between the Os3 and Os2N planes is equal to 71.1(5)°.
