Crystal structure of di-[mu]-iodido-bis­[(dimethyl sulfoxide-[kappa]O)(tri­phenyl­phosphane-[kappa]P)copper(I)]

Michael Knorr, Rodolphe Kinghat, Marek M. Kubicki & Yoann Rousselin
The centrosymmetric dinuclear title compound, [Cu2I2(C2H6OS)2(C18H15P)2], represents the first example of a CuI complex ligated by an O-bound dimethyl sulfoxide ligand. In the crystal, the two tetrahedrally coordinated CuI atoms are bridged by two [mu]2-iodido ligands in an almost symmetrical rhomboid geometry. The loose Cu...Cu contact of 2.9874 (8) Å is longer than the sum of the van der Waals radii of two Cu atoms (2.8 Å), excluding a significant cupriophilic inter­action in the actual...
