Abstract: The asymmetric unit of the title compound, {[Ni(C₇H₃NO₄)(C₁₀H₈N₂)(H₂O)]·H₂O}_n, contains one nickel cation chelated by a 2,2'-bipyridine ligand and further coordinated by two monodentate carboxylate groups belonging to two independent pyridine-3,4-dicarboxylate ligands and one water molecule. The Ni^II atom is six-coordinate, exhibiting octahedral geometry with three N and three O atoms. Each pair of neighbouring Ni^II cations is bridged by two independent pyridine-3,4-dicarboxylate ligands, which are coordinated to two further Ni^II cations through pyridine N atoms to give corrugated layers parallel to the (110) plane. The coordinated and uncoordinated water molecules act as donors in O-HO hydrogen bonds.
