Abstract: The asymmetric unit of the title compound, {[Ni(C₁₀H₈N₂)(H₂O)₄](C₆H₆NO₃S)₂·2H₂O}_n, consists of one [Ni(4,4'-bipy)(H₂O)₄]²⁺ cation (4,4'-bipy is 4,4'-bipyridine), two 4-aminobenzensulfonate (4-abs) anions and two solvent water molecules. The Ni²⁺ ions are linked by the 4,4'-bipy units and form a one-dimensional covalent chain, while the 4-abs anions form one-dimensional zigzag supramolecular chains through hydrogen bonds. These chains are further extended through coordination and solvent water molecules into a three-dimensional supramolecular network.
