Tetra­kis{2-[2-(2,6-dichloro­anilino)phen­yl]ethano­ato-κ²O: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, [Cu₂(C₁₄H₁₀Cl₂NO₂)₄(C₂H₆OS)₂], comprises a Cu^II₂ core that is quadruply bridged by four carboxyl­ate ligands with the dimethyl sulfoxide ligands binding along the Cu...Cu axis. The four carboxyl­ate ligands bind in a bidentate syn–syn bridging mode. Mol­ecules reside on crystallographic inversion centres bis­ecting the mid-point of the Cu...Cu axis. There are no inter­molecular inter­actions of note.
