Abstract

The asymmetric unit of the title compound, [Cu(2)(C(12)H(9)O(2))(4)(C(3)H(7)NO)(2)], contains two independent centrosymmetric dinuclear copper(II) complexes. The central paddle-wheel units are formed by four bridging bidentate naphthalene-1-acetate ligands with two dimethyl-formamide ligands in the axial positions. The unique Cu(II) ions have slightly distorted square-pyramidal coordination geometries. One of the naphthalene rings is disordered over two sets of sites, with refined occpancies of 0.535 (4) and 0.465 (4).
