3,4-Diaminopyridinium 2-carboxy-4,6-dinitrophenolate
In the title salt, C(5)H(8)N(3) (+)·C(7)H(3)N(2)O(7) (-), the pyridine N atom of the 3,4-diamino-pyridine mol-ecule is protonated. The 3,5-dinitro-salicylate anion shows whole-mol-ecule disorder over two orientations with a refined occupancy ratio of 0.875 (4): 0.125 (4). In the crystal, the cations and anions are connected by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dime...

متن کامل4-Aminopyridinium-3-sulfonate monohydrate
The reaction of 4-amino-pyridine and oleum yielded the title hydrated zwitterion, C(5)H(6)N(2)O(3)S·H(2)O. There are two formula units in the asymmetric unit. The H and non-H atoms of both zwitterions lie on a mirror plane except for one sulfonate O atom. The water mol-ecules are also situated on a mirror plane. In the crystal, the zwitterions and water mol-ecules are linked by O-H⋯O and N-H⋯O ...
متن کامل3-Ammonio-4-hydroxybenzoate monohydrate
The title compound, C(7)H(7)NO(3)·H(2)O, which crystallized as a hydrate, was obtained from an extraction of the plant species Saussurea atkinsonii of the asteraceae family collected from the hilly area (Ayubia) of Pakistan during the flowering season. The dihedral angle between the benzene ring and the carboxyl-ate group is 25.64 (5)°. In the crystal, the packing is consolidated by N-H⋯O and O...
متن کامل4-Nitroanilinium 3-carboxy-4-hydroxybenzenesulfonate monohydrate
In the title hydrated salt, C6H7N2O2 (+)·C7H5O6S(-)·H2O, the benzene ring of the cation makes a dihedral angle of 1.32 (19)° with the attached nitro group. In the anion, an intra-molecular O-H⋯O hydrogen bond with an S(6) ring motif is formed between the carb-oxyl and hy-droxy groups; the dihedral angle between the carb-oxyl group and the benzene ring is 8.76 (8)°. The crystal structure exhibit...
