title: Structure of undecacarbonyl[tris(pentafluorophenyl)phosphine]-triangulo- triosmium, a substituted osmium cluster containing a fluorinated triphenylphosphine ligand.
abstract: [Os3(CO)11[P(C6F5)3]], Mr = 1410.87, monoclinic, P2(1)/n, a = 19.058 (1), b = 9.109 (1), c = 20.424 (2) A, beta = 105.53 (1) degree, V = 3416 (1) A3, Z = 4, Dm = 2.74 (2), Dx = 2.743 g cm-3, mu(Mo K alpha, lambda = 0.71073 A) = 113.3 cm-1, F(000) = 2560, T = 297 (1) K, RF = 0.022 for 3529 reflections. The Os atoms form an approximate isosceles triangle. Each Os atom exhibits a distorted octahedral coordination geometry. The carbonyl groups are all terminal and the bulky phosphine ligand is coordinated equatorially.
