In the crystal structure of the title compound, [Zn(C6H2O5)(H2O)3]n, an infinite chain is formed along  by linking of the Zn(H2O)3 entities with one carboxylate group of the furan-2,5-dicarboxylate ligand. Adjacent chains are linked by Owater—H⋯O hydrogen-bonding interactions. The Zn(H2O)3O3 polyhedron displays a distorted octahedral geometry with one weak Zn—Ocarboxylate coordination [2.433 (8) A°] and two water molecules located in axial positions. Except for one of the axial water molecules and two adjacent H atoms, the other atoms (including H atoms) possess site symmetry m.
