Tetra-kis{2-[2-(2,6-dichloro-anilino)phen-yl]ethano-ato-κ 2 O:O′}bis-[(dimethyl sulfoxide-κO)copper(II)](Cu-Cu): A binuclear Cu II complex with the non-steroidal anti-inflammatory drug diclofenac

Abstract

The title compound, [Cu 2(C 14H 10Cl 2NO 2) 4(C 2H 6OS) 2], comprises a Cu II 2 core that is quadruply bridged by four carboxyl-ate ligands with the dimethyl sulfoxide ligands binding along the Cu⋯Cu axis. The four carboxyl-ate ligands bind in a bidentate syn-syn bridging mode. Mol-ecules reside on crystallographic inversion centres bis-ecting the mid-point of the Cu⋯Cu axis. There are no inter-molecular inter-actions of note.
