Abstract: In the title polymer, [Cd(C₁₆H₁₀O₄)(C₁₀H₈N₂)(H₂O)]_n, the Cd^II ion is in a strongly distorted octahedral geometry, being coordinated by two N atoms from a 2,2'-bipyridine ligand, three carboxylate O atoms from two symmetry-related trans-stilbene-4,4'-dicarboxylate dianions and one water molecule. The stilbene ligand lies on an inversion centre at the midpoint of the central C=C bond. This feature generates the polymeric structure: adjacent Cd^II ions are bridged by trans-stilbene-4,4'-dicarboxylate dianions, giving rise to a one-dimensional structure. The coordinated water molecule is involved in interchain O-HO hydrogen bonds.
