catena-Poly[[diaqua­manganese(II)]-μ-7-oxabicyclo­[2.2.1]heptane-2,3-dicarboxyl­ato]

In the title polymer, [Mn(C(8)H(8)O(5))(H(2)O)(2)](n), the Mn(II) atom is in a distorted octa­hedral coordination mode, binding to the bridging O atom of the bicyclo­heptane unit, two O atoms from corresponding carboxyl­ate groups, one carboxyl­ate O atom from a symmetry-related bridging ligand and two water O atoms. This arrangement leads to the formation of polymeric chains propagating parallel to [001]. The crystal structure is stabilized by several O—H⋯O hydrogen-bonding inter­actions involving the coordinated water mol­ecules as donors and the carboxyl­ate O atoms as acceptors.
