A new polymorph of tetra-μ-benzoato-κ⁸O:O′-bis­[(dimethyl sulfoxide-κO)copper(II)]

This paper reports a new polymorph of the title compound, [Cu₂(C₇H₅O₂)₄(C₂H₆OS)₂], a paddlewheel dimer of a tetra­benzoate-bridged dinuclear copper(II) core, with two apically positioned is dordered dimethyl sulfoxide ligands. The Cu—Cu distance is 2.6490 (6)Å.
