In the title complex, [Ni(C(4)H(3)N(2)O(2))(2)(H(2)O)(2)], the Ni(II) ion is located on an inversion center and shows a distorted octa-hedral geometry, defined by two N,O-bidentate 1H-imidazole-4-carboxyl-ate ligands in the equatorial plane and two water mol-ecules in the axial positions. Inter-molecular N-H⋯O hydrogen bonds link the complex mol-ecules into layers parallel to (10[Formula: see text]), which are further linked into a three-dimensional supra-molecular network through O-H⋯O hydrogen bonds.
在标题配合物[Ni(C₄H₃N₂O₂)₂(H₂O)₂]中，Ni(II)离子位于一个对称中心上，呈现出扭曲的八面体几何构型，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。分子间的N-H⋯O氢键将配合物分子连接成平行于(10[化学式：见原文])的层，这些层通过O-H⋯O氢键进一步连接成三维超分子网络。
