In the title complex, [Cd(C(8)H(9)N(2)O(4))(2)(H(2)O)(2)]·2C(3)H(7)NO, the six-coordinate Cd(II) ion is in a slightly distorted octa-hedral environment, defined by two O atoms from two coordinated water mol-ecules and two carboxyl-ate O atoms and two N atoms from two N,O-bidentate 5-carb-oxy-2-propyl-1H-imidazole-4-carboxyl-ate ligands. In the crystal, complex mol-ecules and dimethyl-formamide solvent mol-ecules are linked by O-H⋯O and N-H⋯O hydrogen bonds into a two-dimensional supra-molecular structure. The propyl groups of the ligands are disordered over two conformations with refined occupancies of 0.680 (7) and 0.320 (7).
在标题配合物[Cd(C₈H₉N₂O₄)₂(H₂O)₂]·2C₃H₇NO中，六配位的Cd(II)离子处于略微扭曲的八面体环境中，由两个配位水分子中的两个O原子、两个羧酸根O原子以及来自两个N,O-双齿5-羧基-2-丙基-1H-咪唑-4-羧酸盐配体的两个N原子界定。在晶体中，配合物分子和二甲基甲酰胺溶剂分子通过O—H⋯O和N—H⋯O氢键连接成二维超分子结构。配体的丙基在两种构象上无序，精修占有率分别为0.680 (7)和0.320 (7)。
