Crystal Structure of 2-(4-Chlorophenyl)-1,4,5-triphenyl-(1H)-imidazole

摘要

The title compound, 2-(4-chlorophenyl)-1,4,5-triphenyl-(1H)-imidazole (C₂₇H₁₉N₂Cl), crystallizes in the triclinic space group P1 with the following unit-cell parameters: a = 10.2102(3), b = 10.3193(4), c = 11.2040(4)Å, α = 83.116(3), β = 86.022(3), γ = 66.348(3)° and Z = 2. The crystal structure was solved by direct methods and refined by full-matrix least-squares procedures to a final R-value of 0.0406 for 3039 observed reflections. The phenyl rings and the imidazole ring are planar. The bonds C2-C6, N1-C12, C5-C18 and C4-C24 exhibit significant torsion. The molecules in the unit cell are arranged in layers, and are stabilized by C-H…π interactions. The minimum observed π-π distance is 4.333(1)Å.
