Abstract

Reaction of (NH4)2OsBr6 with excess Na/Hg in THF in the presence of excess tBuNC yields trans-OsBr2(CNBut)4 in high yield. The bis-dichloromethane solvate crystallises from CH2Cl2 solutions and its X-ray crystal structure has been determined. Crystal data: C22H40Br2Cl4N4Os, M = 852.40, monoclinic, space group P21/c, a = 9.702(3) Å, b = 10.143(5) Å, c = 18.497(5) Å, β = 104.28(3)°, U = 1764(1) Å3, Z = 2 for Dc = 1.60 gcm-3. λ(MoKα) = 0.71069 Å (graphite monochromator), μ(MoKα) = 65.44 cm-1, final R = 0.044, Rw = 0.056 from 1105 observed reflections (1777 measured).
