Bis(μ-bicyclo[2.2.1]hept-5-ene-2-exo,3-exo-dicarboxylato-κ²O,O':κ²O'',O''')bis[aqua(2,2'-bipyridine-N,N')manganese(II)] Monohydrate

The title compound, [Mn(μ-C₉H₈O₄)(C₁₀H₈N₂)(H₂O)]₂.H₂O, exists in the crystal as a cyclic dimer about an inversion centre. Two Mn²⁺ ions are double-bridged by two bicyclic dianions which act as tetradentate ligands. The sevenfold coordination around the Mn²⁺ ion is completed by the two bipyridine N atoms and the O atom of a water molecule. The uncoordinated water molecules are positionally disordered and connect the dimers through hydrogen bonding into chains.
