2-Amino-6-methyl-pyridinium 2-carb-oxy-benzoate.

ABSTRACT: In the title mol-ecular salt, C(6)H(9)N(2) (+)·C(8)H(5)O(4) (-), an intra-molecular O-H?O hydrogen bond occurs within the anion, thereby generating an S(7) ring, which may correlate with the fact that both the carb-oxy-lic acid and carboxyl-ate groups are almost coplanar with their attached rings [dihedral angles = 2.9?(3) and 5.2?(3)°, respectively]. In the crystal, each cation is linked to its adjacent anion by two N-H?O hydrogen bonds; the dihedral angle between the pyridine and benzene rings is 2.22?(10)°. The ion pairs are linked by further N-H?O inter-actions.

2-Amino-5-methyl-pyridinium 2-carb-oxy-benzoate.

Project description:In the title salt, C(6)H(9)N(2) (+)·C(8)H(5)O(4) (-), the hydrogen phthalate anion is essentially planar, with a maximum deviation of 0.011 (2) Å. In the crystal structure, the protonated N atom of the pyridine ring and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms of the anion via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. In the hydrogen phthalate anion, there is a very strong, almost symmetric, intra-molecular O-H⋯O hydrogen bond, generating an S(7) motif [O⋯O = 2.382 (3) Å]. Furthermore, these two molecular motif rings are connected by a bifurcated N-H⋯(O,O) hydrogen-bonded motif R(1) (2)(4), forming a supra-molecular ribbon along the b axis. The crystal structure is further stabilized by π-π inter-actions between the cations and anions [centroid-centroid distance = 3.6999 (10) Å].

2-Amino-5-bromo-pyridinium 2-carb-oxy-benzoate.

Project description:The asymmetric unit of the title compound, C(5)H(6)BrN(2) (+)·C(8)H(5)O(4) (-), consists of two crystallographically independent 2-amino-5-bromo-pyridinium cations (A and B) and two 2-carb-oxy-benzoate anions (A and B). Each 2-amino-5-bromo-pyridinium cation is approximately planar, with a maximum deviation of 0.047 (1) Å in cation A and 0.027 (1) Å in cation B. The 2-amino-5-bromo-pyridinium unit in cation A is inclined at dihedral angles of 4.9 (3) and 2.2 (3)° with the phenyl rings of the A and B 2-carb-oxy-benzoate anions, respectively. The corresponding angles for cation B are 3.0 (3) and 5.6 (3)°. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond,which generates an S(7) ring motif. The cations and anions are linked via inter-molecular N-H⋯O and C-H⋯O hydrogen bonds, generating R(2) (2)(8) ring motifs. In the crystal packing, mol-ecules are linked into wave-like chains along [001] via adjacent ring motifs. Short inter-molecular distances between the phenyl and pyridine rings [3.613 (4) and 3.641 (4) Å] indicate the existence of π-π inter-actions. The crystal structure is a non-merohedral twin with a contribution of 0.271 (3) of the minor component.

4-Methyl-pyridinium 2-carb-oxy-4,5-dichloro-benzoate monohydrate.

Project description:In the structure of the 1:1 proton-transfer compound of 4-methyl-pyridine (?-picoline) with 4,5-dichloro-phthalic acid, C(6)H(8)N(+)·C(8)H(3)Cl(2)O(4) (-)·H(2)O, determined at 200?K, the 4,5-dichloro-phthalate anions are bridged by the water mol-ecule through O-H?O(carbox-yl) hydrogen bonds, giving zigzag chains which extend along the c-axis direction. The 4-methyl-pyridinium cations are linked to the chains through single N-H?O(water) hydrogen bonds and occupy the voids within the chains in the one-dimensional structure. The anions have the common 'planar' conformation with a short intra-molecular O-H?O(carbox-yl) hydrogen bond.

2-Amino-5-methyl-pyridinium 2-carb-oxy-acetate.

Project description:In the title mol-ecular salt, C(6)H(9)N(2) (+)·C(3)H(3)O(4) (-), the cation is essentially planar, with a maximum deviation of 0.010?(3)?Å. In the anion, an intra-molecular O-H?O hydrogen bond generates an S(6) ring and results in a folded conformation. In the crystal, the protonated NH group and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms of the anion via a pair of N-H?O hydrogen bonds, forming an R(2) (2)(8) ring motif. Weak inter-molecular C-H?O inter-actions help to further stabilize the crystal structure.

2-Amino-5-chloro-pyridinium 2-carb-oxy-benzoate-benzene-1,2-dicarb-oxy-lic acid (3/1).

Project description:The asymmetric unit of the title compound, 3C(5)H(6)ClN(2) (+)·3C(8)H(5)O(4) (-)·C(8)H(6)O(4), contains three independent 2-amino-5-chloro-pyridinium cations, three independent hydrogen phthal-ate anions and one phthalic acid mol-ecule. In the crystal structure, there are two kinds of supra-molecular tapes. One is formed by two independent cations with two anions through N-H⋯O and C-H⋯O hydrogen bonds. Another one is formed by the other cation and anion, and the phthalic acid mol-ecule via N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds. These two tapes are connected by an O-H⋯O hydrogen bond, forming a double-tape structure.
