In the title coordination polymer, [Ni(C5H4NO2S)2(H2O)2]n, the NiII ion is located on an inversion centre and is octahedrally coordinated by two N and two O atoms of four symmetry-related and deprotonated pyridine-4-sulfinate (ps) ligands together with two water molecules in axial positions. The ps− anions, acting as μ2-bridging ligands, link neighbouring NiII ions into a chain structure along the c axis. These polymeric chains are extended into a three-dimensional framework via intermolecular O—H⋯O hydrogen bonds with participation of the water molecules.
