title: catena-Poly[[diaqua-nickel(II)]-μ-7-oxabicyclo-[2.2.1]heptane-2,3-di-carboxyl-ato].
abstract: In the crystal structure of the title compound, [Ni(C(8)H(8)O(5))(H(2)O)(2)](n), the Ni(II) cation is in a Jahn-Teller-distorted octahedral coordination environment binding to two O atoms from water molecules, the bridging O atom of the bicycloheptane unit, two carboxylate O atoms from different carboxylate groups and one carboxylate O atom from a symmetry-related bridging ligand. The crystal structure is made up from layers propagating parallel to the bc plane.
