Crystal structure of 2-amino-5-nitropyridinium sulfamate
Acta Crystallographica Section E: Crystallographic Communications, 2015 The title molecular salt, C5H6N3O2+ ·H2NO3S−, was obtained from the reaction of sulfamic acid with 2-amino-5-nitropyridine. A proton transfer from sulfamic acid to the pyridine N atom occurred, resulting in the formation of a salt.

Crystal structure of the co-crystal salt 2-amino-6-bromopyridinium 2,3,5,6-tetrafluorobenzoate
Acta Crystallographica Section E: Crystallographic Communications, 2019 The asymmetric unit of the co-crystal salt 2-amino-6-bromopyridinium 2,3,5,6-tetrafluorobenzoate, C5H6BrN2+·C7HF4O2−, contains one pyridinium cation and one benzoate anion. In the crystal, the aminopyridinium cationic unit forms two hydrogen bonds to the
