2-Amino-4-methyl-pyridinium 2-hy-droxy-benzoate.

ABSTRACT: The asymmetric unit of the title mol-ecular salt, C(6)H(9)N(2) (+)·C(7)H(5)O(3) (-), contains two cations and two anions. Both the salicylate anions contain an intra-molecular O-H?O hydrogen bond, which generates an S(6) ring. Both the 2-amino-4-methyl-pyridine mol-ecules are protonated at their pyridine N atoms. In the crystal, both cations form two N-H?O hydrogen bonds to their adjacent anions, forming ion pairs. Further N-H?O links generate sheets lying parallel to the ab plane. In addition, weak C-H?O bonds and aromatic ?-? stacking inter-actions [centroid-centroid distances = 3.5691?(9) and 3.6215?(9)?Å] are observed between the cations and anions.
