2-(2,6-Di­chloro­phen­yl)-1-pentyl-4,5-diphenyl-1H-imidazole

The title compound, C₂₆H₂₄Cl₂N₂, crystallizes with two independent mol­ecules (1 and 2) in the asymmetric unit. In mol­ecule 1, the two phenyl and 2,6-di­chloro­phenyl rings are inclined to the imidazole ring at angles of 74.12 (14), 26.13 (14) and 67.30 (14)°, respectively. In mol­ecule 2, due to the different mol­ecular environment in the crystal, the corresponding angles are different, viz. 71.72 (15), 16.14 (15) and 80.41 (15)°, respectively. In the crystal, mol­ecules 1 and 2 are linked by C—H...Cl inter­actions, and inversion-related 2 mol­ecules are linked by C—H...π inter­actions. There are no other significant inter­molecular inter­actions present.

1-{(E)-[(2-Fluoro-5-nitro­phen­yl)imino]­meth­yl}naphthalen-2-ol

The title mol­ecule, C₁₇H₁₁FN₂O₃, is nearly planar [maximum deviation = 0.197 (1) Å] and the mol­ecular conformation is stabilized by an N—H...O hydrogen bond forming an S(6) ring motif. The H atom of the intra­molecular hydrogen bond was found to be disordered over two sites and thus both the hy­droxy and keto tautomers are simultaneously present in the solid. Refinement of the occupancy of this site suggests that the hy­droxy form is the major component [occupancy refined to 0.59 (3):0.41 (3)]. Bond lengths are also largely consistent with dominance of the hy­droxy form. In the crystal, mol­ecules are linked by C—H...O hydrogen bonds, forming layers parallel to (101). π–π stacking inter­actions [centroid–centroid distances = 3.5649 (9) and 3.7579 (9) Å] inter-connect these layers.

2-(4-Chloro­phen­yl)-4,5-diphenyl-1-(prop-2-en-1-yl)-1H-imidazole

The title compound, C₂₄H₁₉ClN₂, crystallizes with two independent mol­ecules in the asymmetric unit. The prop-2-enyl substituents on the imidazole rings adopt similar conformations in the two mol­ecules. The 4-and 5-substituted phenyl rings and the benzene ring make dihedral angles of 67.06 (8), 5.61 (8) and 41.09 (8)°, respectively, with the imadazole ring in one mol­ecule and 71.53 (8), 28.85 (8) and 41.87 (8)°, respectively, in the other. The crystal structure features C—H...π inter­actions and weak π–π stacking inter­actions [centroid–centroid distances = 3.6937 (10) and 4.0232 (10) Å] between the chloro­phenyl rings, which form a three-dimensional supramolecular structure.

2-(4-Bromo­phen­yl)-4-(4-meth­oxy­phen­yl)-6,7,8,9-tetra­hydro-5H-cyclo­hepta­[b]pyridine

In the title compound, C₂₃H₂₂BrNO, the cyclo­heptane ring adopts a chair conformation. The pyridine ring makes dihedral angles of 58.63 (15) and 8.27 (16)° with the benzene rings. The dihedral angle between the benzene rings is 56.68 (17)°. The crystal packing features C—Br...π inter­actions [Br...centroid distances= 3.813 (2) and 3.839 (2) Å; C—Br...centroid = 126.25 (10) and 138.31 (10)°, respectively, forming a three dimensional supramolecular architecture.

2,4,5-Triphenyl-1-(prop-2-en-1-yl)-1H-imidazole

In the title compound, C₂₄H₂₀N₂, one of the ring C atoms and one of the ring N atoms are disordered over two sets of sites in a 0.615 (3):0.385 (3) ratio. The two parts of the disordered imidazole ring adopt an envelope conformation, with the undisordered ring N atom as the flap, displaced by −0.118 (6) and 0.226 (7) Å, respectively, in the two disorder components from the plane through the other ring atoms. The crystal structure features C—H...N hydrogen bonds and C—H...π inter­actions, which lead to the formation of infinite chains along [010].
