چکیده
In the title mol-ecule, C(16)H(23)N(3)O(3), the dihedral angle between the benzimidazole and nitro group planes is 5.34 (9)° and the dihedral angle between the benzimidazole and aliphatic chain mean planes is 73.23 (5)°. The C-C-C-C torsion angles (about 176°) of the nonyl group indicate an all-anti-periplanar conformation. In the crystal, adjacent mol-ecules are linked by pairs of N-H⋯O hydrogen bonds into inversion dimers. These mol-ecules are further connected through C-H⋯O inter-actions, building tapes parallel to (22).

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 synpe...
