Tetraaquabis[4-(4H-1,2,4-triazol-4-yl)benzoato-κN1]nickel(II) decahydrate

In the title compound, [Ni(C9H6N3O2)2(H2O)4]·10H2O, the NiII ion lies on a twofold rotation axis and displays a slightly distorted octahedral geometry defined by two N atoms from two monodentate 4-(1,2,4-triazol-4-yl)benzoate ligands and four water molecules, two of which also lie on the twofold rotation axis. In the crystal, the complex molecules and uncoordinated water molecules are linked via intermolecular O—H...N and O—H...O hydrogen bonds, forming a three-dimensional supramolecular network. π–π interactions between the benzene rings provide additional stability of the crystal packing [centroid–centroid distance = 3.792 (2) Å]
