The title compound, [Mn(C7H3NO4)(C12H6N2O2)(H2O)(2)]center dot 2H(2)O, is a neutral mononuclear Mn-II complex. The Mn-N bond to the pyridine-2,6-dicarboxylate ligand lies along a crystallographic twofold rotation axis. The Mn2+ cation has a distorted pentagonal-bipyramidal configuration, coordinated by three N atoms, one from the pyridine-2,6-dicarboxylate ligand and two from the chelating 1,10-phenanthroline-5,6-dione ligand. The remaining four coordination sites are occupied by O atoms, two from the pyridine-2,6-dicarboxylate ligand and two from water molecules. The asymmetric unit also contains a solvent water molecule. The crystal structure is stabilized by a network of O-H center dot center dot center dot O hydrogen-bonding interactions in a three-dimensional supramolecular structure.
