Abstract: In the title compound, [Zn(C₁₄H₈N₂O₆)(H₂O)₄]_n, the 2,2'-dihydroxy-5,5'-diazenediyldibenzoate ligand acts as a carboxylate bridge, leading to the formation of a polymeric chain running along the [10] direction. The Zn^II atom is hexa-coordinated in a distorted octahedral geometry by six O atoms [Zn-O = 2.055 (4)-2.132 (3) Å] from two carboxylate ligands and four water molecules. The crystal packing is stabilized by intermolecular O-HO, O-HN and C-HO hydrogen bonds, and two - interactions. The centroid-centroid distances are 3.803 (16) and 3.804 (17) Å.
