The title compound, C7H5Cl2NO2?[systematic name: 1,3-di-chloro-2-methyl-5-nitro-benzene], crystallizes in the chiral space group?P212121?with a Flack parameter of ?0.03?(5). The methyl C atom, the Cl atoms and the N atom of the nitro substituent all lie extremely close to the plane of the benzene ring; the deviations are 0.028?(3)?? for the methyl C atom, ?0.016?(1) and 0.007?(1)?? for the two Cl atoms, and ?0.017?(3)?? for the nitro N atom. Hence, no significant steric hindrance of the methyl group by the?ortho?halogen atoms is observed. The nitro group is inclined to the benzene ring by 9.8?(3)°. In the crystal, mol-ecules are linked by weak C—H?O and C—H?Cl hydrogen bonds, forming layers parallel to the?ab?plane.
