Abstract: The title complex, [Cu₂(NAA)₄(DMSO)₂]·2(HNAA)·2DMSO [NAA = -naphthylacetate (C₁₂H₉O₂) and DMSO = dimethyl sulfoxide (C₂H₆OS)], consists of a centrosymmetric dinuclear cage unit, in which two Cu^II atoms are separated by 2.626 (1) Å and bridged by four bidentate carboxylate groups of naphthylacetates, with an average Cu-O distance of 1.961 (2) Å. Each Cu^II atom has a five-coordinate square-pyramidal environment with the dimethyl sulfoxide molecule at the apical position. The Cu-O bond length to the DMSO molecule is 2.160 (2) Å.
