In the title compound, {[Na(C(8)H(9)N(2)O(4))(H(2)O)]·0.5H(2)O}(n), the Na(+) ion is coordinated by two bridging water mol-ecules, one N atom and three O atoms from three 4-carb-oxy-2-propyl-1H-imidazole-5-carboxyl-ate (H(2)pimdc) ligands. Adjacent Na(+) ions are linked alternately by two water O atoms and two carb-oxy O atoms into a chain along [001]. These chains are connected through the coordination of the carboxyl-ate O atoms to the Na(+) ions, forming a three-dimensional structure. An intra-molecular O-H⋯O hydrogen bond and inter-molecular N-H⋯O and O-H⋯O hydrogen bonds are present in the crystal structure.
在标题化合物{[Na(C₈H₉N₂O₄)(H₂O)]·0.5H₂O}ₙ中，Na⁺离子由两个桥连水分子、一个N原子以及来自三个4-羧基-2-丙基-1H-咪唑-5-羧酸盐（H₂pimdc）配体的三个O原子配位。相邻的Na⁺离子通过两个水分子O原子和两个羧基O原子交替连接，沿[001]方向形成一条链。这些链通过羧酸盐O原子与Na⁺离子的配位作用相连，形成三维结构。晶体结构中存在分子内O—H⋯O氢键以及分子间N—H⋯O和O—H⋯O氢键。
