The mol-ecule of the binuclear title complex, [Cu(2)(C(8)H(7)O(2))(4)(C(10)H(8)N(2))(2)]·2H(2)O, is located on an inversion centre. The Cu atoms are bridged by two O atoms of the monodentate phenyl-acetate groups [Cu-O = 1.9808 (14) and 2.3668 (14) Å]. The longer of the two bridging Cu-O bonds takes the apical position of the distorted square-pyramidal environment of the Cu atom, which is completed by two N atoms of the chelate 2,2'-bipyridine ligand [Cu-N = 2.0107 (17) and 2.0234 (16) Å]. The mol-ecules are assembled into stacks along [100] through π-π inter-actions with inter-planar distances of 3.630 (4) and 3.407 (3) Å; the resulting stacks are further connected into a three-dimensional supra-molecular architecture by O-H⋯O and C-H⋯O hydrogen-bonding inter-actions.
双核标题配合物[Cu₂(C₈H₇O₂)₄(C₁₀H₈N₂)₂]·2H₂O的分子位于一个对称中心上。铜原子由单齿苯乙酸酯基团的两个氧原子桥联[Cu - O = 1.9808 (14) 和2.3668 (14) Å]。两条桥联Cu - O键中较长的一条占据铜原子扭曲四方锥环境的顶端位置，该环境由螯合2,2'-联吡啶配体的两个氮原子补充完整[Cu - N = 2.0107 (17) 和2.0234 (16) Å]。分子通过π - π相互作用沿[100]方向堆积成堆叠结构，平面间距离为3.630 (4) 和3.407 (3) Å；所得的堆叠结构通过O - H⋯O和C - H⋯O氢键相互作用进一步连接成三维超分子结构。
