2,4-Dinitro-N,N-methylphenylaniline

In the title compound, C₁₃H₁₁N₃O₄, the substituted aromatic ring has a slightly deformed chair conformation and the unsubstituted ring a deformed boat conformation. The dihedral angle between the mean plane of the rings is 62.9 (1)°. The o-nitro group is twisted out of the plane of the phenyl ring. Short C—HO intermolecular contacts stabilize the three-dimensional structure.
