In the title compound, C(10)H(9)Cl(2)NO(3), 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 dichloro-all-yloxy 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 inter-actions at a distance of 3.060 (3) Å, forming sheets approximately parallel to [-201] and generating R(2) (2)(18) rings. π-π contacts between benzene rings in adjacent sheets, with centroid-centroid distances of 3.671 (2) Å, stack mol-ecules along c.
在标题化合物C(10)H(9)Cl(2)NO(3)中,苯环与硝基平面之间的二面角为39.1 (1)°,而苯环与通过二氯烯丙氧基单元的三个C原子和两个Cl原子的平面之间的二面角为40.1 (1)°。在晶体中,与硝基形成的C—H⋯O氢键沿b轴形成链。这些链通过距离为3.060 (3) Å的Cl⋯O相互作用的反演相关对相连,形成大致平行于[-201]的片层,并生成R(2) (2)(18)环。相邻片层中苯环之间的π-π接触,质心间距为3.671 (2) Å,沿c轴堆积分子。
