2-Amino-5-methyl-pyridinium 2-hy-droxy-benzoate.

ABSTRACT: In the title compound, C(6)H(9)N(2) (+)·C(7)H(5)O(3) (-), the protonated 2-amino-5-methyl-pyridinium cation and the 2-hy-droxy-benzoate anion are both essentially planar, with maximum deviations of 0.026?(2) and 0.034?(1)?Å, respectively. The anion is stabilized by an intra-molecular O-H?O hydrogen bond, which forms an S(6) ring motif. In the solid state, the anions are linked to the cations via pairs of inter-molecular N-H?O hydrogen bonds forming R(2) (2)(8) ring motifs. The crystal structure is further stabilized by N-H?O and C-H?O inter-actions which link the mol-ecules into chains along [010]. A ?-? stacking inter-action [centroid-centroid-distance = 3.740?(2)?Å] is also observed.
