The title compound, C2H10N22+·C7H3NO42-·2H2O, forms a three-dimensional hydrogen-bonded framework structure in which both of the amine groups of ethylenediamine are protonated and participate in a total of six hydrogen-bonding interactions with carboxylate O-atom acceptors of the anions as well as the water molecules. The cations lie on crystal-lographic inversion centres and adopt extended conformations, while the anions have twofold rotational symmetry. This results in the pyridine N atom and its ortho-related CH group being disordered over two 50% occupancy sites.
