In the title complex, [Cu(C9H4O6)(H2O)3]n, the CuII cation exhibits a distorted square-pyramidal coordination geometry involving five O atoms from two monodentate 5-carboxybenzene-1,3-dicarboxylate anions and three water molecules. The 5-carboxybenzene-1,3-dicarboxylate anions bridge CuII cations into zigzag polymeric chains running along the b-axis direction. These chains are further linked by O-HO hydrogen bonds between coordinating water molecules or carboxyl groups and carboxylate groups into a three-dimensional supramolecular architecture. In the crystal, - stacking is observed between parallel benzene rings of adjacent chains, the centroid-centroid distances being 3.584 (3) and 3.684 (3) Å.
