In the title compound, C10H9Cl2NO3, the dihedral angle between the benzene ring and the plane of the nitro group is 39.1 (1)°, while that between the benzene ring and the plane through the three C and two Cl atoms of the dichloroallyloxy unit is 40.1 (1)°. In the crystal, C—H⋯O hydrogen bonds to the nitro groups form chains along the b axis. These chains are linked by inversion-related pairs of Cl⋯O interactions at a distance of 3.060 (3) Å, forming sheets approximately parallel to [-201] and generating R22(18) rings. π–π contacts between benzene rings in adjacent sheets, with centroid–centroid distances of 3.671 (2) Å, stack molecules along c.
