Abstract
The title compound, C7H4N4O4, was Obtained by nitration of 5-nitro-1H-indaz ole. It has a planar indazole ring, with the N1-bound nitro group almost co planar with the ring [twist angle 3.9(2)degrees], while the C5-bound nitro group is twisted by 19.2(2)degrees out of the plane of the molecule. The mo lecules in the crystal structure are arranged in planes. They are connected to each other by weak C-H ... O hydrogen bonds, with C ... O distances of 3.276 (3) Angstrom.
