The title cocrystal, C6H7N1O2·C6H4N2O5, owes its formation to an intermolecular hydrogen bond between the O—H and N—O groups [O...O 2.461 (2) Å]. The angle between the planes of the rings of the molecules is 88.82 (7)°. The crystal structure exhibits overlap between the rings of the molecules in the  direction. The rings are stacked in the crystal, with a mean interplanar distance of 3.318 (2) Å.
