Abstract: In the crystal structure of the title compound, [Cu(C₈H₈O₅)(H₂O)₂]_n, the Cu(II) cation is in a Jahn-Teller distorted six-coordination by two O atoms from water molecules, by the bridging O atom from the bicyclo moiety, by two carboxylate O atoms from two different carboxylate groups and by one carboxylate O atom from a symmetry-related bridging ligand.The polymeric structure is made up from double-strands propagating parallel to the c axis that are held together via intermolecular O-HO hydrogen bonds.
