Abstract: The title compound, C₃H₁₂N₂²⁺·C₇H₃NO₄^2-·C₇H₅NO₄·2.5H₂O, is a proton-transfer system obtained from pyridine-2,6-dicarboxylic acid and propane-1,3-diamine. Both neutral and dianionic forms of the diacid are observed in the crystal structure. The molecular structure contains also the diprotonated form of propane-1,3-diamine as well as water molecules. In the crystal structure, a wide range of hydrogen-bonding interactions connect the various fragments into a supramolecular structure.
