Abstract: In the title polymeric complex, {[Cu(C₇H₄O₅S)(C₁₀H₈N₂)(H₂O)]·H₂O}_n, each Cu atom is coordinated by a water molecule, two 3-sulfonatobenzoate ligands and two N atoms from one 2,2'-bipyridine molecule, in the shape of a square pyramid. The bridging 3-sulfonatobenzoate ligands extend the molecular structure into a one-dimensional chain. The coordinated water molecule forms an intramolecular hydrogen bond with the carboxyl group and an intermolecular hydrogen bond with the solvent water molecule. The extensive hydrogen-bonding network between the sulfonate groups and the solvent water molecules of two polymer chains generates ring structures, which form an infinite ladder-like pattern extending along the a axis.
