| Abstract | In the title compound, C10H9N2 +·C16H9O8 −·2H2O, both the cation and anion possess crystallographically imposed centres of symmetry, causing the nitrogen-bound H atom in the 4-(4-pyridyl)pyridinium cation and the acidic H atom of the carboxylate groups at the 3 and 3′ positions in the anion to be disordered over two positions with equal occupancies. In the crystal packing, the cations, anions and water molecules are connected by O—H⋯O, C—H⋯O and N—H⋯N hydrogen bonds, forming layers parallel to (2 0). These layer are further connected into a three-dimensional supramolecular network by O—H⋯O hydrogen bonds involving the water molecules as H-atom donors and by weak π–π stacking interactions between neighbouring benzene and pyridine rings, with centroid–centroid distances of 3.756 (5) Å. |
