The title compound, [Ni(SO₄)(C₁₀H₈N₂)(C₂H₆O₂)(H₂O)]_n, contains two crystallographically unique Ni^II atoms, each lying on a twofold rotation axis and having a slightly distorted octahedral environment. It is isotypic with the previously reported Cu^II analog [Zhong et al. (2011). Acta Cryst. C67, m62-m64]. One Ni^II atom is coordinated by two N atoms from two bridging 4,4'-bipyridine (4,4'-bipy) ligands, two O atoms from two sulfate ions and two aqua O atoms. The second Ni^II atom is surrounded by two N atoms from 4,4'-bipy ligands and four O atoms, two from bridging sulfate ions and from two ethane-1,2-diol ligands. The sulfate anion acts as a bridging ligand, linking adjacent Ni^II atoms, leading to the formation of linear Ni1-Ni2-Ni1-Ni2 chains along the a-axis direction. Adjacent chains are further bridged by 4,4'-bipy ligands, resulting in a two-dimensional layered polymer parallel to (001). In the crystal, the polymeric layers are linked by extensive O-HO hydrogen-bonding interactions involving the O atoms of the water molecules and the ethane-1,2-diol molecules, resulting in a three-dimensional supramolecular network.
