The fused pyrazole and pyrimidine rings in the title compound, C 22H19BrN4O, are almost coplanar, their planes being inclined to one another by 2.08 (13)°. The dihedral angles formed by the mean plane of the fused ring system and the phenyl and benzene rings are 16.21 (4) and 82.84 (4)°, respectively. An intramolecular N - H⋯N hydrogen bond is observed. In the crystal, molecules form inversion dimers via pairs of C - H⋯O hydrogen bonds. π-π interactions, with centroid-centroid distances of 3.4916 (9) Å, connect the dimers into a three-dimensional network. © Bassoude et al. 2013.

In the title compound, C15H22N2O, the octyl group adopts an all-trans conformation. In the crystal, molecules form centrosymmetric dimers with an R 2 2 (8) graph-set motif, linked by pairs of N - H⋯O hydrogen bonds. In addition, C - H⋯O contacts are observed. © Belaziz et al. 2012.

In the title compound, C19H30N2O, the fused ring system is essentially planar, the maximum deviation from the mean plane being 0.013(2)Å for the N atom bearing the dodecyl chain. The 1-dodecyl group is almost perpendicular to the 1H-benzo[d]imidazol-2(3H)-one plane as indicated by the dihedral angle of 82.9(2)°between planes through the fused ring system and the first three C atoms of the chain. The C-C-C-C torsion angles (about ±179°) of the dodecyl group indicate an antiperiplanar conformation. In the crystal, inversion dimers are formed by pairs of N-H⋯O hydrogen bonds.

The fused pyrazole and pyrimidine rings in the title compound, C 13H10ClN3, are almost coplanar, their planes being inclined to one another by 0.8 (2)°. The mean plane of the fused ring system is nearly coplanar with the phenyl ring, as indicated by the dihedral angle between their planes of 9.06 (7)°.

In the title compound, C15H14N2O, the fused five- and six-membered ring system is essentially planar, the maximum deviation from the mean plane being 0.009(1)Å. The benzimidazol-2(3H)-one residue is nearly perpendicular to the benzyl ring, forming a dihedral angle of 77.41(6)°. In the crystal, inversion dimers are formed by pairs of N - H⋯O hydrogen bonds; these dimers are linked by weak C - H⋯O interactions into a two-dimensional array in the (102) plane.
