Crystal structure of di-?-iodido-bis-[(dimethyl sulfoxide-?O)(tri-phenyl-phosphane-?P)copper(I)].

ABSTRACT: 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 Cu(I) atoms are bridged by two ?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 inter-action in the actual dimer. C-H?O and C-H?I hydrogen bonding interactions as well as C-H??(aryl) interactions stabilize the three-dimensional supramolecular network.

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 Cu(I) 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 inter-action in the actual dimer.
