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.
