Abstract: The title coordination polymer, [Zn(C7H4O6S)(H2O)4]n, comprises octahedral Zn atoms bonded to two carboxylate O atoms of the acid ligands and four water molecules. The zinc(II) ions are bridged by carboxylate moieties, creating a one-dimensional chain structure. The Zn-O bond distances lie in the range 2.074 (3)-2.118 (3) Å. The water molecules are involved in hydrogen bonds.
