Propane-1,3-diaminium pyridine-2,3-dicarboxylate monohydrate

Abstract: The title compound, C₃H₁₂N₂²⁺·C₇H₃NO₄^2-·H₂O, contains one dicationic fragment, one dianionic fragment and one water molecule. The two carboxylate groups of the pyridine-2,3-dicarboxylate (pydc^2-) fragment are almost perpendicular to each other [dihedral angle 83.10 (8)°]. In the crystal structure, intermolecular N-HO, N-HN, O-HO and C-HO hydrogen bonds and edge-to-face - stacking, together with ion pairing, are responsible for extending the structure in three dimensions, resulting in a supramolecular network.
