Abstract: In the title compound, {[Ni(C₇H₄O₅S)(C₁₂H₁₀N₂)(H₂O)₂]·0.25H₂O}_n, the Ni^II atom has a distorted octahedral environment formed by two N and four O atoms. The 1,2-di-4-pyridylethylene ligands, which lie on inversion centers, function as ₂-bridging ligands to form a linear chain. The 2-sulfonatobenzoate ligands protrude alternately on both sides of the linear chain and chelate to the Ni^II atoms through one carboxylate O atom and one sulfonate O atom.
