Abstract: In the title compound, {[Zn(C₁₀H₈O₆)(C₅H₅N)₂(H₂O)]}_n, the coordination geometry around the Zn^II atom is distorted square-pyramidal, and the Zn-OH₂ bond at the apical position lies on a twofold axis. The bis-monodentate benzene-1,4-dioxyacetate ligand has inversion symmetry and acts as a bridge to link Zn atoms to form an infinite zigzag chain. Hydrogen bonds between the coordinated water molecule and the free carboxylate O atoms link the chains along the b axis into a two-dimensional layer.
