Abstract: The asymmetric unit of the title compound, (C₇H₇N₂)₂[Mn(C₇H₃O₄N)₂(H₂O)₂]·2H₂O, contains one half-anion, one cation and one uncoordinated water molecule. The Mn^II atom, lying on a centre of symmetry, is coordinated in a distorted octahedral arrangement by two O atoms and two N atoms of two pyridine-2,4-dicarboxylate and two O atoms of two aqua ligands. In the crystal structure, intermolecular O-HO and N-HO hydrogen bonds and - interactions link the molecules into a three-dimensional supramolecular framework.
