Abstract: In the title complex, [Zn(1,4-BDOA)(H₂O)₄]_n or [Zn(C₁₀H₈O₆)(H₂O)₄]_n (where 1,4-BDOA^2- is the benzene-1,4-dioxyacetate dianion), the Zn^II atom and the 1,4-BDOA^2- ligand build up a one-dimensional polymer chain along c. The Zn^II atom, located on an inversion center, shows an octahedral coordination geometry, defined by two carboxyl O atoms of different benzene-1,4-dioxyacetate ligands and four water molecules. Adjacent Zn^II atoms are bridged by bis-monodentate carboxylate groups of the centrosymmetric 1,4-BDOA^2- ligands, to furnish the one-dimensional chain along the c axis; the ZnZn separation within the polymer is 14.717  (3)  Å. A hydrogen-bonded supramolecular architecture is formed via O-HO intermolecular hydrogen bonds.
