2-(4-Meth-oxy-phen-yl)-1-pentyl-4,5-di-phenyl-1H-imidazole

2-(4-Bromo-phen-yl)-1-pentyl-4,5-diphenyl-1H-imidazole

The title compound, C26H25BrN2, is isomorphous with the chloro derivative [2-(4-chloro-phen-yl)-1-pentyl-4,5-diphenyl-1H-imidazole; Mohamed et al. (2013 ▶). Acta Cryst. E69, o846-o847]. The two phenyl rings and the 4-bromo-phenyl ring are oriented at dihedral angles of 30.1 (2), 64.3 (3) and 42.0 (2)°, respectively, with respect to the imidazole ring. In the crystal, mol-ecules stack in columns along the b-axis direction, however, there are no significant inter-molecular inter-actions present.

2-(4-Chloro-phen-yl)-1-pentyl-4,5-di-phenyl-1H-imidazole

In the title compound, C26H25ClN2, the phenyl rings and the 2-(4-chloro-phen-yl) group make dihedral angles of 30.03 (11), 67.49 (12) and 41.56 (11)°, respectively, with the imidazole ring. In the crystal, the mol-ecules inter-act with each other via very weak C-H⋯π contacts, forming layers parallel to (110).

2-(2,6-Di-chloro-phen-yl)-1-pentyl-4,5-diphenyl-1H-imidazole

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