چکیده
The asymmetric unit of the title compound, C(16)H(13)NO(3), contains two independent mol-ecules related approximately by a pseudo-twofold rotation axis. The dihedral angle between the nitro-benzene and methyl-phenyl rings is 42.18 (6)° in one mol-ecule and 12.97 (6)° in the other. In both mol-ecules, the nitro group is slightly twisted away from the attached benzene ring. In the crystal structure, the mol-ecules are stacked along the b axis and are linked via C-H⋯O and C-H⋯π inter-actions.
