【 摘 要 】

In the crystal of the title polymeric complex, [Cd(C12H8O4)(H2O)2]n, the CdII cation, located on a twofold rotation axis, is coordinated by two water mol­ecules and chelated by two phenyl­enediacrylate anions (mpda) in a distorted octa­hedral geometry. The mpda anions bridge the CdII cations, forming helical chains propagating along the c-axis direction. The mpba anion has twofold symmetry with two benzene C atoms located on the twofold rotation axis. In the crystal, O—H⋯O hydrogen bonds link the polymeric helical chains into a three-dimensional supra­molecular architecture.
