In the title compound, [Zn(C5H3N4)2], the ZnII cation is in a nearly regular tetrahedral coordination by purinate ligands. Each purinate ligand chelates two ZnII cations through two imidazole N atoms of the purinate anion ligand, leading to the formation of a three-dimensional network.

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 ZnII 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.
