title: Triaqua-(2,2'-bipyridine)(5-nitro-isophthal-ato-κO)nickel(II) monohydrate.
abstract: In the title compound, [Ni(C(8)H(3)NO(6))(C(10)H(8)N(2))(H(2)O)(3)]·H(2)O, the Ni(II) cation is six-coordinated by a chelating 2,2'-bipyridine ligand, one carboxyl-ate O atom from a 5-nitro-isophthalate dianion and three water mol-ecules, with a slightly distorted cis-NiN(2)O(4) octa-hedral geometry. The neutral complex is isolated, in contrast to coordination polymers formed by Mn(II), Co(II) and Cu(II) with the same ligand set, but forms an extensive network of O-H⋯O hydrogen bonds between the coordinated and uncoordinated water mol-ecules and carboxyl-ate groups of the 5-nitro-isophthalate ions.
