The title coordination polymer, [Zn(C8H4N4O2)(H2O)]n, was prepared by the hydrothermal reaction of zinc nitrate and 2-(1H-tetrazol-5-yl)benzoic acid. Two types of coordinated zinc cations exist in the structure. One is tetrahedrally coordinated by two O and two N from two ligands, the other is octahedrally coordinated by two N and two O from two ligands at equatorial sites and by two O atoms of water molecules at axial sites, resulting in a two-dimensional framework. The crystal structure is stabilized by intramolecular O-HO and O-HN hydrogen bonds.
