Abstract
[OsI2 (CO)2 (C3H9N)(C 18H15P)], Mr = 821.4, monoclinic, P2 1/n, a = 15.011 (3), b = 11.316 (4), c = 16.155 (2) Å3 = 106.55 (1) °, V = 2630 (1) Å3, Z= 4, Dx = 2.07 Mg m-3, ,λ(Mo Kα) = 0.7107 Å μ = 7.25 mm-l, F(000) = 1528, T= 298 K, R = 0.058, wR = 0.051 for 2432 observed reflections. The Os atom is six coordinate in a slightly distorted octahedral geometry. Two I ligands and two CO groups are mutually in a cis form. The Os-C(2) bond length [1.75 (2) Å] is significantly shorter than that of Os-C(1) [1.82 (2)Å]. Two Os-I bond distances [2.698 (2), 2.705 (3) Å] are among the shortest Os-I bond lengths reported in the literature. © 1992 International Union of Crystallography.
