Tetraaquabis(3,5-di-4-pyridyl-1,2,4-triazolato-κN)nickel(II) dihydrate

Abstract

The NiII atom in the title compound, [Ni(C12H8N5)2(H2O)4]·2H2O, lies on a center of inversion and is coordinated by the N atoms of two 3,5-di-4-pyridine-1,2,4-triazolate ligands and by four water O atoms in a slightly distorted octahedral geometry. The coordinated and uncoordinated water molecules interact with the N-heterocycles through O—H...N and O—H...O hydrogen bonds, generating a three-dimensional supramolecular architecture.
