Crystal structure of di-μ-iodido-bis[(dimethyl sulfoxide-κO)(triphenylphosphane-κP)copper(I)]

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 μ2-iodido ligands in an almost symmetrical rhomboid...

Description
Summary: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 μ2-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 dimer. C—H...O and C—H...I hydrogen bonding interactions as well as C—H...π(aryl) interactions stabilize the three-dimensional supramolecular network.
