Abstract
The 2-amino-5-nitropyridine molecule of the title complex, C5H5N3O2.C5 H4N2O3, is planar, while the nitro group in 3-nitro-2-pyridone is tilt ed away from the mean plane by 27.9(3)degrees. The C-C bond distance b etween the substituted atoms in the pyridone ring, 1.439(3) Angstrom, is slightly lengthened due to the electron-withdrawing effect of the a djacent carbonyl and nitro groups. The molecules are linked into centr osymmetric tetramers which are stacked in layers along the c axis. The layers are held together by weak C-H ... O hydrogen bends and van der Waals interactions.
