2-Amino-4-methylpyridinium 2-hydroxy-3,5-dinitrobenzoate
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...

The asymmetric unit of the title salt, C(6)H(9)N(2) (+)·C(7)H(5)O(6)S(-), contains two crystallographically independent 2-amino-5-methylpyridinium cations and two sulfosalicylate anions. In the crystal structure, the sulfonate group of each 3-carb-oxy-4-hy-droxy-benzene-sulfonate anion inter-acts with the corresponding 2-amino-5-methyl-pyridinium cation via a pair of N-H⋯O hydrogen bonds, formi...
متن کامل2-Amino-5-chloropyridinium 3-carboxy-4-hydroxybenzenesulfonate
The asymmetric unit of the title salt, C(5)H(6)ClN(2) (+)·C(7)H(5)O(6)S(-), contains two independent 2-amino-5-chloro-pyridinium cations and two independent 3-carb-oxy-4-hy-droxy-benzene-sulfonate anions. In both anions, the O atoms of the sulfonate group are disordered over two sets of positions, with occupancy ratios of 0.47 (5):0.53 (5) and 0.50 (8):0.50 (8). In each anion, an intra-molecula...
متن کاملMethyl 2-amino-4-(3-chloropropoxy)-5-methoxybenzoate
The asymmetric unit of the title compound, C(12)H(16)ClNO(4), contains two crystallographically independent mol-ecules. The benzene rings of the two independent mol-ecules are oriented at a dihedral angle of 88.50 (3)°. Intra-molecular N-H⋯O hydrogen bonds involving the methoxybenzoate carbonyl group in each molecule result in the formation of two planar, six-membered rings, oriented at dihedra...
متن کامل2-Amino-5-bromopyridinium 3-carboxy-4-hydroxybenzenesulfonate
The asymmetric unit of the title salt, C(5)H(6)BrN(2) (+)·C(7)H(5)O(6)S(-), contains two independent 2-amino-5-bromo-pyridinium cations and two independent 3-carb-oxy-4-hy-droxy-benzene-sulfonate anions. The hy-droxy and carboxyl groups of the anions are involved in intra-molecular O-H⋯O hydrogen bonds, which generate S(6) ring motifs. In the crystal structure, the ions are linked by N-H⋯O and ...
