μ(3)-Bromido-oxidotri-μ(3)-sulfido-tris­(triphenyl­phosphane-κP)­tri­copper(I)­tungsten(VI)

The title complex, [Cu(3)WBrOS(3)(C(18)H(15)P)(3)], a neutral heavily distorted cubane-like W/S/Cu cluster, was self-assembled from ammonium trithio­tungstate(VI), cuprous bromide and triphenyl­phosphane in N,N-dimethyl­formamide. The average Cu—Br, Cu—S and W—μ(3)-S bond lengths are 2.731 (2), 2.318 (2) and 2.256 (2) Å, respectively, in the distorted cubane-like skeleton. The W atom exhibits tetra­hedral geometry, formed by one terminal O atom and three μ(3)-S atoms; the W—O bond length is 1.728 (6) Å. Each Cu atom is coordinated by one P atom from a triphenyl­phosphane ligand, and two μ(3)-S and one μ(3)-Br atoms, forming a distorted tetra­hedral coordination geometry.
