【 摘 要 】

In the title polymeric complex salt, {[Ni(C8H4NO2)(C10H8N2)(H2O)3](C8H4NO2)}n, the NiII cation is coordinated by a 4-cyano­benzoate anion, two 4,4′-bi­pyridine ligands and three water mol­ecules in a distorted N2O4 octa­hedral geometry. The 4,4′-bi­pyridine ligands bridge the NiII cations to form polymeric chains of the title complex cations, propagating along the c-axis direction. The dihedral angle between the pyridine rings of the 4,4′-bi­pyridine ligand is 24.9 (6)°. In the crystal, the uncoordinating 4-cyano­benzoate anions link with the complex cations via O—H⋯O hydrogen bonds into a three-dimensional supra­molecular architecture. Weak C—H⋯O, C—H⋯N inter­actions and π–π stacking [centroid-to-centroid distances = 3.566 (4) and 3.885 (4) Å] are also observed in the crystal.
