Poly[(μ3-hydrogenphosphato)(4H-1,2,4-triazole-κN 1)zinc]

Abstract

The asymmetric unit of the title compound, [Zn(HPO4)(C 2H3N3)] 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-H⋯O and O-H⋯O hydrogen bonds between the phosphate groups and the triazole ligands.
