In the title compound, [Zn(C(9)H(4)O(6))(C(12)H(12)N(2))(H(2)O)(2)], the Zn(II) atom is five-coordinated by two N atoms from a 4,4'-dimethyl-2,2'-bipyridine ligand, one O atom from a 5-carb-oxy-benzene-1,3-dicarboxyl-ate ligand and two water mol-ecules in a distorted trigonal-bipyramidal geometry. The complex mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds and partly overlapping π-π inter-actions [centroid-centroid distance = 4.017 (2) Å] into a three-dimensional supra-molecular network.

在标题化合物[Zn(C₉H₄O₆)(C₁₂H₁₂N₂)(H₂O)₂]中，Zn(II)原子由来自4,4'-二甲基-2,2'-联吡啶配体的两个N原子、来自5-羧基苯-1,3-二羧酸酯配体的一个O原子以及两个水分子以扭曲的三角双锥几何构型进行五配位。配合物分子通过分子间O—H⋯O氢键和部分重叠的π-π相互作用[质心-质心距离 = 4.017 (2) Å]连接成三维超分子网络。
