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.

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, ...[more]

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

Project description: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 π-π stacking inter-action [centroid-centroid-distance = 3.740 (2) Å] is also observed.
