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-HN and O-HO hydrogen bonds, forming a three-dimensional supramolecular network. - interactions between the benzene rings provide additional stability of the crystal packing [centroid-centroid distance = 3.792 (2) Å].
