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.

The title compound, [Cu(2)(C(14)H(10)Cl(2)NO(2))(4)(C(2)H(6)OS)(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.
