Tris(diphenyl-propyl-phosphine-κP)-μ(2)-iodido-tri-μ(3)-sulfido-sulfidotricopper(I)tungsten(VI).

ABSTRACT: A neutral W/S/Cu cluster, [Cu(3)WIS(4)(C(15)H(17)P)(3)], was formed by the reaction of tetra-thio-tungstate(VI), CuI and diphenyl-propyl-phosphine (dpp) in dimethyl-formamide. The title compound exhibits a neutral half-open cubane-like skeleton, with Cu-I bonds of 2.8056 (8) and 2.9008 (8) Å, and one Cu⋯I short contact of 3.1722 (6) Å. The W atom exhibits a tetra-hedral coordination geometry through bonding to three μ(3)-S and one terminal S atom. The three Cu(I) atoms are in two different coordination environments: one Cu atom exhibits a triangular coordination geometry being coordinated by one P atom from dpp and two μ(3)-S atoms, whereas the remaining two Cu centers are tetra-hedrally coordinated, forming the CuPIS(2) core.
