چکیده
The title mol-ecule, C(17)H(25)N(3)O(3), is built up from fused six- and five-membered rings linked to a -C(10)H(21) chain. The fused-ring system is essentially planar, the largest deviation from the mean plane being 0.009 (2) Å. The chain is roughly perpendic-ular to this plane, making a dihedral angle of 79.5 (2)°. In the crystal, N-H⋯O hydrogen bonds build infinite chains along [010]. There are channels in the structure containing disordered hexane. The contribution of this solvent to the scattering power was suppressed using the SQUEEZE option in PLATON [Spek (2009 ▶). Acta Cryst. D65, 148-155].

1-n-Decyl-5-nitro-1H-benzimidazol-2(3H)-one
The benzimidazolone part of the title mol-ecule, C(17)H(25)N(3)O(3), is almost planar (r.m.s. deviation = 0.016 Å) and its mean plane is aligned at 7.9 (4) ° with respect to the mean plane of the nitro substituent. In the crystal, two mol-ecules are disposed about a center of inversion, generating a N-H⋯O hydrogen-bonded cyclic dimer with a 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...

The asymmetric unit of the title compound, C(27)H(36)N(4), contains two independent mol-ecules. Except for the atoms of the decyl chain, the non-H atoms of each mol-ecule are approximately coplanar (r.m.s. deviations = 0.075 and 0.164 Å) and the -CH(2)CH(2)CH(2)- link connecting the two benzimidazolyl fused-ring systems is slightly opened up at the middle C atom. The decyl substituent adopts an...
