摘要：
The molecule of 3,5-difluoro-4-nitropyridine N-oxide, C5H2F2N2O3, is twisted around the C-NO2 bond by 38.5 (1)degrees, 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 pi electrons.
