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

In the title compound, [Ni(C(9)H(6)N(3)O(2))(2)(H(2)O)(4)]·10H(2)O, the Ni(II) 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].
