Abstract: A neutral W/S/Cu cluster, [Cu₃WIS₄(C₁₅H₁₇P)₃], was formed by the reaction of tetrathiotungstate(VI), CuI and diphenylpropylphosphine (dpp) in dimethylformamide. 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 CuI short contact of 3.1722 (6) Å. The W atom exhibits a tetrahedral coordination geometry through bonding to three 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 ₃-S atoms, whereas the remaining two Cu centers are tetrahedrally coordinated, forming the CuPIS₂ core.
