Abstract:
In the title compound, {[Zn(C(9)H(9)N(5))(2)(H(2)O)(2)](ClO(4))(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-pyrid-yl)ethyl-idene-4H-1,2,4-triazol-4-amine (L) ligands and two O atoms from coordinated water mol-ecules in a slightly distorted octa-hedral environment. Each L ligand bridges symmetry-related Zn(II) ions, forming a two-dimensional layer with a (4,4) grid. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds connect perchlorate counter-anions to the layers.
