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

ABSTRACT: In the title compound, C(5)H(6)BrN(2) (+)·C(7)H(5)O(3) (-), the 2-amino-5-bromo-pyridinium cation and 2-hy-droxy-benzoate anion are essentially planar with maximum deviations of 0.020?(1) and 0.018?(2)?Å, respectively. The anion is stabilized by an intra-molecular O-H?O hydrogen bond, which generates an S(6) ring motif. In the crystal, the cations and anions are linked by N-H?O hydrogen bonds into chains propagating along [010]. The chains contain R(2) (2)(8) ring motifs. The structure is further stabilized by ?-? stacking inter-actions [centroid-centroid distances = 3.4908?(10) and 3.5927?(10)?Å] and also features short Br?O contacts [2.9671?(13)?Å].

Project description:In the 5-chloro-salicylate anion of the title salt, C5H6BrN2 (+)·C7H4ClO3 (-), an intra-molecular O-H⋯O hydrogen bond with an S(6) graph-set motif is formed, so that the anion is essentially planar with a dihedral angle of 1.3 (5)° between the benzene ring and the carboxyl-ate group. In the crystal, the protonated N atom and the 2-amino group of the cation 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 crystal structure also features N-H⋯O and weak C-H⋯O inter-actions, resulting in a layer parallel to the (10-1) plane.

Project description: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.
