4-Aminopyridinium hydrogen succinate

H.-K. Fun, J. John, S. R. Jebas and T. Balasubramanian

Abstract: In the title salt, C₅H₇N₂⁺·C₄H₅O₄^-, the asymmetric unit comprises an aminopyridinium cation and a hydrogen succinate anion as protonation of the aromatic N atom of the 4-aminopyridine molecule has occurred. The crystal packing is stabilized by intermolecular O-HO and N-HO hydrogen bonds that lead to a two-dimensional array. Short C-HO contacts are also present.
