The 5-nitro-1H-indazol-1-yl moiety of the title compound, C15H10BrN3O3, is approximately planar, with the largest deviation from the mean plane being 0.079 (3) Å. The fused-ring system is virtually perpendicular to the mean plane through the 1-phenylethanone group, making a dihedral angle of 89.7 (2)°. In the crystal, pairs of molecules form inversion dimers via Br...O interactions [3.211 (2) Å]. The dimers are connected by C—H...O and C—H...N non-classical hydrogen bonds, in addition to π–π interactions [intercentroid distance = 3.6411 (12) Å], forming a three-dimensional network.
