Abstract: In the title coordination polymer, [Zn(C₅H₂N₂O₄)(H₂O)]_n, each Zn^II atom is six-coordinated by one N atom [Zn-N = 2.250 (7) Å] and four O atoms [Zn-O = 2.289 (6)-2.435 (6) Å] from three different HIDC ligands (H₃IDC = imidazole-4,5-dicarboxylic acid), and one water molecule [Zn-O = 2.311 (6) Å] in a highly distorted octahedral geometry. In the crystal structure, a three-dimensional supramolecular network is constructed via hydrogen-bonding interactions involving the water molecules, uncoordinated imidazole N atom and carboxylate O atoms.
