Abstract: The title compound, [Ni(SO₄)(C₅H₅N)(H₂O)₃]_n, was synthesized by the hydrothermal reaction of NiSO₄·6H₂O, pyridine and water. The central Ni^II atom is coordinated in a distorted octahedral environment by a pyridine N atom, three aqua O atoms and two O atoms of bridging sulfate anions, yielding a zigzag chain. A three-dimensional network is generated via complex hydrogen bonds involving the sulfate and aqua ligands and a pyridine C-H group.
