Abstract: In the complex molecule of the title compound, [Zn(C₉H₅O₆)₂(H₂O)₄]·2H₂O, zinc(II) is six-coordinated by two O atoms from two monodentate 2,4-dicarboxybenzoate ligands and four O atoms from water molecules. The complex possesses a crystallographically imposed centre of symmetry. In the crystal packing, complex molecules and water molecules are connected by strong intermolecular O-HO hydrogen bonds, resulting in an extended three-dimensional network. A zigzag chain of hydrogen-bonded water molecules running along the c axis is observed.
