STRUCTURE OF 1,2,2,2,3,3,3,4,4,4-DECACARBONYL-1,2-3,4-DI-MU-HYDRIDO-1-TRICYCLOHEXYL-PHOSPHINE-3-TRIISOPROPYLPHOSPHINEPLATINUMTRIOSMIUM(2PT-OS)(3OS-OS)

[Os3Pt(mu-H)2(CO)10{P(C6H11)3}{P(iC3H7)3}], M(r) = 1488.5, monoclinic, P2(1)/c, a = 10.678 (2), b = 15.924 (4), c = 27.237 (5) angstrom, beta = 100.92 (2)-degrees, V = 4547 (2) angstrom 3, Z = 4, D(x) = 2.17 g cm-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 115.85 cm-1, F(000) = 2776, T = 298 K, R = 0.035 for 3227 unique observed reflections. The metal skeleton is of the butterfly form, with a non-bonding Pt...Os(3) distance of 3.837 (1) angstrom, and a butterfly angle, defined by the torsion angle Pt-Os(1)-Os(2)-Os(3), of 98.2 (1)-degrees. The pseudo-octahedral ligand sphere on Os(3) is skewed out of the Os3 plane by ca 11.5-degrees.
