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].
在双核铜（II）标题配合物[Cu₂(C₉H₇O₄)₄(C₂H₃N)₂]中，一个对称中心位于Cu-Cu键的中点。Cu（II）原子与其四个配位的O原子呈扭曲的平面正方形排列，而氮原子和另一个Cu（II）原子位于顶端位置。整个分子看起来像一个桨轮。在晶体中，分子链沿着b轴通过C-H⋯O氢键和相邻分子苯环之间的π-π滑移相互作用组装在一起[质心-质心距离 = 3.6929 (3) Å，滑移 = 0.641 (1) Å]。
