2-Amino-4-methylpyridinium 6-carboxypyridine-2-carboxylate sesquihydrate
In the title compound, C(6)H(9)N(2) (+)·C(7)H(4)NO(4) (-)·1.5H(2)O, extensive O-H⋯O, O-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds, as well as ion pairing, π-π stacking inter-actions [centroid-centroid distances = 3.4690 (8) and 3.6932 (8) Å between aromatic rings] occur in the crystal. There are hydrogen-bonding inter-actions between water mol-ecules, which result in cyclic tetra-meric water clusters....

In the anion of the title mol-ecular salt, C(6)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (-), the two nitro groups are twisted from the attached benzene ring with dihedral angles of 27.36 (10) and 4.86 (11)°. 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 and C-H⋯O inter-actions and are furthe...

In the title compound, C(14)H(13)ClN(+)·I(-)·H(2)O, the cation is nearly planar and exists in an E configuration; the dihedral angle between the pyridinium and benzene rings is 0.98 (17)°. The cations stack in an anti-parallel manner along the a axis through two π-π inter-actions between the pyridinium and benzene rings [centroid-centroid distances 3.569 (2) and 3.6818 (13) Å, respectively]. Th...
متن کامل2-Amino-6-methylpyridinium 4-methylbenzenesulfonate
In the asymmetric unit of the title salt, C6H9N2 (+)·C7H7O3S(-), there are two independent 2-amino-6-methyl-pyridinium cations and two independent 4-methyl-benzene-sulfonate anions. Both cations are protonated at their pyridine N atoms and their geometries reveal amine-imine tautomerism. In the 4-methyl-benzene-sulfonate anions, the carboxyl-ate groups are twisted out of the benzene ring planes...
متن کامل2-Amino-6-methylpyridinium 4-hydroxybenzoate
In the title mol-ecular salt, C6H9N2 (+)·C7H5O3 (-), the dihedral angle between the benzene ring and the CO2 group in the anion is 6.1 (2)°. In the crystal, the cation and anion are linked by N-H⋯O and C-H⋯O hydrogen bonds, and the anions are connected by O-H⋯O hydrogen bonds, forming a three-dimensional network.
