چکیده
The benzimidazolone part of the mol-ecule of the title compound, C(15)H(21)N(3)O(3), is almost planar (r.m.s. deviation = 0.007 Å) with its mean plane aligned at a dihedral angle of 10.4 (3)° with respect to the mean plane of the nitro substituent. In the crystal, two mol-ecules are disposed about a center of inversion, generating an N-H⋯O hydrogen-bonded cyclic dimer with R(2) (2)(8) graph-set motif.

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...
