The one-dimensional polymer poly[[aqua­(2,2′-bipyridine)cadmium(II)]-μ-trans-stilbene-4,4′-dicarboxyl­ato]

In the title polymer, [Cd(C(16)H(10)O(4))(C(10)H(8)N(2))(H(2)O)](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—H⋯O hydrogen bonds.
