2,3-Dimethyl-6-nitro-2H-indazole

In the mol­ecule of the title compound, C(9)H(9)N(3)O(2), 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) (...

Descripción
Sumario:In the mol­ecule of the title compound, C(9)H(9)N(3)O(2), 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.
