title: Crystal structure of catena-poly[[di-aqua-cadmium(II)]-μ-3,3'-(1,3-phenyl-ene)diacrylato].
abstract: In the crystal of the title polymeric complex, [Cd(C12H8O4)(H2O)2] n , the Cd(II) cation, located on a twofold rotation axis, is coordinated by two water mol-ecules and chelated by two phenyl-enediacrylate anions (mpda) in a distorted octa-hedral geometry. The mpda anions bridge the Cd(II) 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 supra-molecular architecture.
