Abstract: In the title compound, {[Zn(C₉H₉N₅)₂(H₂O)₂](ClO₄)₂}_n, the Zn^II ion lies on an inversion center and is coordinated by two triazolyl N atoms and two pyridyl N atoms from four symmetry-related N-1-(3-pyridyl)ethylidene-4H-1,2,4-triazol-4-amine (L) ligands and two O atoms from coordinated water molecules in a slightly distorted octahedral environment. Each L ligand bridges symmetry-related Zn^II ions, forming a two-dimensional layer with a (4,4) grid. In the crystal structure, intermolecular O-HO hydrogen bonds connect perchlorate counter-anions to the layers.
