Pentaaqua-1²O,2³O-bis(2,2'-bipyridine)-1²N,N';2²N,N'--biphenyl-2,2'-dicarboxylato-1:2²O:O'-biphenyl-2,2'-dicarboxylato-1O-dimanganese(II) tetrahydrate

Abstract: The title compound, [Mn₂(C₁₄H₈O₄)₂(C₁₀H₈N₂)₂(H₂O)₅]·4H₂O, has been obtained under hydrothermal conditions. In the asymmetric unit, there are two crystallographically distinct Mn^II ions, bridged by a dpa^2- ligand (H₂dpa = diphenic acid), which are sixfold coordinated by four O atoms and two N atoms. The O atoms coordinated to one Mn atom are from three water molecules and one dpa^2- ligand, while those coordinated to the other Mn atom are from two water molecules and two dpa^2- ligands. In the crystal structure, centrosymmetric dimers are formed via a pair of intermolecular O-HO hydrogen bonds.
