2-Amino-5-methylpyridinium 4-carboxybutanoate

In the title salt, C6H9N2+·C5H7O4−, the 2-amino-5-methylpyridinium cation is essentially planar, with a maximum deviation of 0.008 (1) Å. In the crystal, the protonated N atom and the 2-amino group are hydrogen bonded to the carboxylate O atoms via a pair of N—H...O hydrogen bonds, forming an R22(8) ring motif. The 4-carboxybutanoate anions are linked via O—H...O hydrogen bonds. The crystal structure is further stabilized by weak C—H...O interactions.
