Abstract: In the crystal structure of the title compound, {[Cu(C6H2O5)(C10H8N2)(H2O)]·2H2O}n, an infinite chain parallel to [110] is formed by the linking of Cu(H2O)(2,2'-bipyridine) units through a furan-2,5-dicarboxylate bridge. The CuII atom shows a square-pyramidal geometry, with one furan-2,5-dicarboxylate O atom in the apical position. The dihedral angle between the planes of the furan ring and the bipyridine molecule is 83.88 (7)°. Owater-H...O hydrogen bonds connect adjacent chains, generating a layer motif parallel to (001).
