In the title compound, CHBrFNO, the nitro-substituted benzene ring and the 4-fluoro-phenyl ring form a dihedral angle of 65.73 (7)°. In the crystal, mol-ecules are linked into chains by C-H⋯O hydrogen bonds running parallel to the -axis direction. The crystal packing is consolidated by C-F⋯π inter-actions and π-π stacking inter-actions, and short Br⋯O [2.9828 (13) Å] contacts are observed. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H⋯H (17.4%), O⋯H/H⋯O (16.3%), Br⋯H/H⋯Br (15.5%), Br⋯C/C⋯Br (10.1%) and F⋯H/H⋯F (8.1%) contacts.
在标题化合物CHBrFNO中，硝基取代的苯环与4-氟苯基环形成的二面角为65.73 (7)°。在晶体中，分子通过平行于a轴方向的C—H⋯O氢键连接成链。晶体堆积通过C—F⋯π相互作用和π-π堆积相互作用得以巩固，并且观察到短的Br⋯O [2.9828 (13) Å]接触。晶体结构的 Hirshfeld 表面分析表明，对晶体堆积贡献最大的是H⋯H（17.4%）、O⋯H/H⋯O（16.3%）、Br⋯H/H⋯Br（15.5%）、Br⋯C/C⋯Br（10.1%）和F⋯H/H⋯F（8.1%）接触。
