Abstract

In the title compound, [Ni(C8H3NO6)(C12H10N2)(H2O)]n, the NiII atom is octahedrally coordinated by two cis N atoms from two different 1,2-bis(4-pyridyl)ethylene (bpe) ligands, two O atoms from one chelating carboxyl group of the 5-nitroisophthalic acid (nip) ligand, one O atom from another monodentate nip ligand and one O atom from a water molecule, forming a three-dimensional network structure. Intermolecular O—H...O hydrogen bonding stabilizes this arrangement. The asymmetric unit of the structure contains one NiII atom, one water molecule, one nip ligand and two half-molecules of the bpe ligand with an inversion centre at the mid-point of the central C=C bond.
