4-Aminopyridinium hydrogen succinate

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—H...O and N—H...O hydrogen bonds that lead to a two-dimensional array. Short C—H...O contacts are also present.
