Abstract
The molecule of 3,5-difluoro-4-nitropyridine N-oxide, C5H2F2N2O3, is twisted around the C—NO2 bond by 38.5 (1)°, while the 3,5-diamino analogue, 3,5-diamino-4-nitropyridine N-oxide monohydrate, C5H6N4O3·H2O, adopts a planar conformation stabilized by intramolecular hydrogen bonds, with a significant redistribution of π electrons.
