catena-Poly[[[aqua­pyridine­zinc(II)]-μ(2)-3,3′-(p-phenyl­ene)diacrylato] pyridine solvate]

The title compound, {[Zn(C(12)H(8)O(4))(C(5)H(5)N)(H(2)O)]·C(5)H(5)N}(n), has been prepared by hydro­thermal reaction. The Zn(II) atom is six-coordinated by four carboxyl­ate O atoms of two p-phenylenediacrylate (ppda(2−)) ligands, one N atom of a pyridine mol­ecule and one O atom of a water mol­ecule in a distorted octa­hedral environment. The carboxyl­ate groups of the ppda(2−) anions are in a bridging–chelating mode, in which two O atoms chelate one Zn(2+) ion. These connections result in an extended chain structure. Parallel packing of the chains forms a two-dimensional network with inter­molecular edge-to-face inter­actions. Further linkages between the layers through O—H⋯O hydrogen-bonding inter­actions result in a three-dimensional supra­molecular architecture with one-dimensional recta­nglar channels.
