Abstract: The asymmetric unit of the title compound, [Zn(HPO₄)(C₂H₃N₃)]_n, contains one Zn²⁺ cation, one (HPO₄)^2- anion and a 1,2,4 triazole ligand. The Zn²⁺ cation is coordinated in a quite regular tetrahedral geometry by O atoms from three phosphate groups and a tertiary N atom from the triazole ring. Each phosphate anion is connected to three Zn^II cations, leading to a series of corrugated organic-inorganic layers parallel to the ac plane. The overall structure involves stacking of complex hybrid organic-inorganic layers along the b axis. Cohesion in the crystal is ensured by an infinite three-dimensional network of N-HO and O-HO hydrogen bonds between the phosphate groups and the triazole ligands.
