Abstract
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 CuII atom together with its four coordinated O atoms are in a distorted planar square arrangement while the nitrogen and the other CuII atom are located in apical positions. The whole molecule 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 interactions between the benzene rings of neighbouring molecules [centroid–centroid distance = 3.6929 (3) Å and slippage = 0.641 (1) Å].
