Abstract
In the molecule of the title compound, C9H9N3O2, the indazole ring system is almost planar [maximum deviation = 0.019 (3) Å for the C atom bearing the nitro group]. In the crystal structure, intermolecular C—H⋯O interactions link the molecules into centrosymmetric dimers, forming R 2 2(18) ring motifs. Aromatic π–π contacts between indazole rings [centroid–centroid distances = 3.632 (1) and 3.705 (1) Å] may further stabilize the structure.
