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.

2,4,5-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].
