Tetra­kis[μ-2-(meth­oxy­carbon­yl)benzoato-κ(2) O (1):O (1′)]bis­[(acetonitrile-κN)copper(II)](Cu—Cu)

In the binuclear copper(II) title complex, [Cu(2)(C(9)H(7)O(4))(4)(C(2)H(3)N)(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 nitro­gen and the other Cu(II) 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].
