在标题配位聚合物[Ni(C5H4NO2S)2(H2O)2]n中，NiII离子位于反转中心，由四个对称性相关的去质子化吡啶-4-亚磺酸(PS)配体的两个N和两个O原子与两个水分子在轴向位置上进行八面体配位。PS-−阴离子作为μ2-桥联配体，将相邻的NiII离子沿着c轴连接成链结构。这些聚合物链通过分子间O-H⋯O氢键在水分子的参与下延伸到三维骨架中。
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.
