The benzimidazolone residue in the title mol-ecule, C10H9N3O3, is almost planar, with the largest deviation from the mean plane being 0.016 (2) Å for the C atom linked to the nitro group. This plane is nearly perpendicular to the 1-allyl chain as indicated by the C-N-C-C torsion angle of 90.9 (3)°. The fused-ring system makes a dihedral angle of 5.6 (3)° with the nitro group, leading to a synperiplanar conformation. In the crystal, zigzag supra-molecular chains are formed along the a axis by N-H⋯O hydrogen bonds.
标题分子C₁₀H₉N₃O₃中的苯并咪唑酮残基几乎呈平面状，与平均平面偏差最大的是与硝基相连的C原子，偏差为0.016 (2) Å。如C-N-C-C扭转角为90.9 (3)°所示，该平面几乎垂直于1-烯丙基链。稠环体系与硝基的二面角为5.6 (3)°，形成顺叠构象。在晶体中，通过N-H⋯O氢键沿a轴形成锯齿状超分子链。
