Abstract: The title compound, [Mn(C₁₂H₆N₂O₂)(H₂O)₄]SO₄·2H₂O, was obtained by the reaction of manganese(II) sulfate with an equivalent of 1,10-phenanthroline-5,6-dione in aqueous solution. Mn(II) is hexacoordinated in a distorted octahedral geometry by the two N atoms from the phenanthroline-dione ligand and the O atoms from four coordinated water molecules. Both the cation and anion lie about mirror planes. The structure is stabilized by an extensive network of O-HO hydrogen bonds.
