Abstract

In the title salt, C(6)H(9)N(2) (+)·C(5)H(7)O(4) (-), the 2-amino-5-methyl-pyridinium 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 carboxyl-ate O atoms via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The 4-carb-oxy-butano-ate anions are linked via O-H⋯O hydrogen bonds. The crystal structure is further stabilized by weak C-H⋯O inter-actions.
