【 摘 要 】

In the title compound, C5H2Cl2N2O3, the nitro group is essentially coplanar with the aromatic ring, with a twist angle of 4.00 (6)° and a fold angle of 2.28 (17)°. The crystal structure exhibits a herringbone pattern with the zigzag running along the b axis. The herringbone layer-to-layer distance is 3.0075 (15) Å, with a shift of 5.150 (4) Å. Neighboring mol­ecules are tilted at a 57.83 (4)° (ring-to-ring) angle with each other. The nitro group on one mol­ecule points to the N-oxide group on the neighboring one, with an inter­molecular O⋯N(nitro) distance of 3.1725 (13) Å.
