catena-Poly[[[aqua­(2,2′-bipyridine-κ²N,N′)copper(II)]-μ-furan-2,5-di­carboxyl­ato-κ²O²:O⁵] dihydrate]

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 Cu^II 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)°. O_water—H...O hydrogen bonds connect adjacent chains, generating a layer motif parallel to (001).
