In the title compound, {[Zn(C9H9N5)2(H2O)2](ClO4)2}n, the ZnII 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 ZnII ions, forming a two-dimensional layer with a (4,4) grid. In the crystal structure, inter­molecular O—H⋯O hydrogen bonds connect perchlorate counter-anions to the layers.
