catena-Poly[aquabis(μ-3-chlorobenzoato-κ² O:O′)zinc]

In the polymeric title compound, [Zn(C7H4ClO2)2(H2O)] n , the Zn ^II cation is located on a twofold rotation axis and is coordinated by carboxylate O atoms of four monodentate chlorobenzoate anions and by one water molecule, located on a twofold rotation axis, in a distorted square-pyramidal geometry. In the anion, the carboxylate group is twisted away from the attached benzene ring by 44.16 (11)°. The chlorobenzoate anion bridges Zn ^II cations, forming polymeric chains running along the c-axis direction. O - H...O hydrogen bonds between coordinating water molecules and carboxylate groups link adjacent chains into layers parallel to the bc plane.
