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

ABSTRACT: In the salicylate anion of the title salt, C(5)H(7)N(2) (+)·C(7)H(5)O(3) (-), an intra-molecular O-H?O hydrogen bond generating an S(6) ring motif is observed. In the crystal structure, the cations and anions are linked into a two-dimensional network parallel to the ab plane by N-H?O and C-H?O hydrogen bonds. The network contains R(2) (2)(7) and R(1) (2)(4) ring motifs. Weak ?-? inter-actions between the benzene and pyridinium rings [centroid-centroid distance = 3.688?(1)?Å] are also observed.

In the salicylate anion of the title salt, C(5)H(7)N(2) (+)·C(7)H(5)O(3) (-), an intra-molecular O-H⋯O hydrogen bond generating an S(6) ring motif is observed. In the crystal structure, the cations and anions are linked into a two-dimensional network parallel to the ab plane by N-H⋯O and C-H⋯O hydrogen bonds. The network contains R(2) (2)(7) and R(1) (2)(4) ring motifs. Weak π-π inter-actions between the benzene and pyridinium rings [centroid-centroid distance = 3.688 (1) Å] are also observed. ...[more]

Project description: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].

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

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.

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.

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.

Project description:In the title mol-ecular salt, C(5)H(8)N(3) (+)·C(7)H(5)O(3) (-), the 2,3-diamino-pyridinium cation is essentially planar, with a maximum deviation of 0.006 (2) Å.
