Catena-Poly[[[aqua-pyridine-zinc(II)]-μ(2)-3,3'-(p-phenyl-ene)diacrylato] pyridine solvate].

ABSTRACT: 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 hydro-thermal reaction. The Zn(II) atom is six-coordinated by four carboxyl-ate O atoms of two p-phenylenediacrylate (ppda(2-)) ligands, one N atom of a pyridine mol-ecule and one O atom of a water mol-ecule in a distorted octa-hedral environment. The carboxyl-ate 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 inter-molecular edge-to-face inter-actions. Further linkages between the layers through O-H⋯O hydrogen-bonding inter-actions result in a three-dimensional supra-molecular architecture with one-dimensional recta-nglar channels.

Project description:In the title compound, {[Zn(C(12)H(8)O(4))(C(12)H(8)N(2))(H(2)O)]·0.5H(2)O}(n), each Zn(II) atom is six-coordinated by two N atoms from one 1,10-phenanthroline (phen), three carboxyl-ate O atoms from two different L ligands [H(2)L = 3,3'-(p-phenyl-ene)diacrylic acid] and one water mol-ecule in a distorted octa-hedral environment.
