In the crystal structure of the title compound, [Cu(C(7)H(5)O(2))(2)(C(12)H(12)N(2))(H(2)O)], the Cu(II) ion is penta-coordinated in a distorted square-pyramidal geometry by two O atoms of two benzoate anions and two N atoms of a 5,5'-dimethyl-2,2'-bipyridine ligand occupying the basal plane, and a water O atom located at the apical site. In the crystal structure, O-H⋯O hydrogen bonds link the mol-ecules into a supra-molecular structure. The crystal studied was a racemic twin, as suggested by the Flack parameter of 0.584 (14).
在标题化合物[Cu(C₇H₅O₂)₂(C₁₂H₁₂N₂)(H₂O)]的晶体结构中，Cu(II)离子通过两个苯甲酸根阴离子的两个O原子和占据基面的5,5'-二甲基-2,2'-联吡啶配体的两个N原子以扭曲的四方锥几何构型进行五配位，以及位于顶点位置的一个水分子O原子。在晶体结构中，O—H⋯O氢键将分子连接成超分子结构。所研究的晶体是一个外消旋孪晶，弗拉克参数为0.584 (14)表明了这一点。
