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

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 π-π stacking inter-actions [centroid-centroid distances = 3.5691 (9) and 3.6215 (9) Å] are observed between the cations and anions.

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
