In the binuclear copper(II) title complex, [Cu2(C9H7O4)4(C2H3N)2], an inversion centre is situtated at the mid-point of the Cu-Cu bond. The Cu(II) atom together with its four coordinated O atoms are in a distorted planar square arrangement while the nitro-gen and the other Cu(II) atom are located in apical positions. The whole mol-ecule looks like a paddle-wheel. In the crystal, chains are assembled along the b axis through C-H⋯O hydrogen bonds and slipped π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.6929 (3) Å and slippage = 0.641 (1) Å]. |
