In the title compound, [Cu(C(6)H(2)O(5))(H(2)O)(3)](n), an infinite chain is formed along [001] by linking of the Cu(OH(2))(3)O(4) cluster with one carboxyl-ate group of the furan-2,5-dicarboxyl-ate ligand. Adjacent chains are linked by O(water)-H⋯O hydrogen-bonding inter-actions. The Cu(OH(2))(3)O(4) cluster displays a penta-gonal bipyrimadal geometry with two weak coordinations [Cu-O(furan) = 2.790 (2) Å) and Cu-O(carboxyl-ate) = 2.684 (2) Å] and two water mol-ecules located in axial positions.
