In the title compound, [Mn(C4H3N2O2)2(H2O)2], the Mn(II) ion is located on a twofold rotation axis and displays a distorted octa-hedral coordination environment, defined by two N,O-bidentate 1H-imidazole-4-carboxyl-ate ligands in the equatorial plane and two water mol-ecules in axial positions. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional supra-molecular network. π-π stacking inter-actions between the imidazole rings [centroid-centroid distances = 3.5188 (15) and 3.6687 (15) Å] further stabilize the structure.
在标题化合物[Mn(C₄H₃N₂O₂)₂(H₂O)₂]中，Mn(II)离子位于一个二重旋转轴上，呈现出扭曲的八面体配位环境，由赤道平面上的两个N,O-双齿1H-咪唑-4-羧酸酯配体和轴向位置的两个水分子界定。在晶体中，O—H⋯O和N—H⋯O氢键将分子连接成三维超分子网络。咪唑环之间的π-π堆积相互作用[质心-质心距离 = 3.5188 (15) 和3.6687 (15) Å]进一步稳定了结构。
