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

Project description: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.

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

Project description:The title compound, C27H28N2O, is a lophine (2,4,5-triphenyl-1H-imidazole) derivative with an n-pentyl chain on the amine N atom and a 4-meth-oxy substituent on the benzene ring.

Project description:The title compound, C24H19ClN2, crystallizes with two independent mol-ecules in the asymmetric unit. The prop-2-enyl substituents on the imidazole rings adopt similar conformations in the two mol-ecules. 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 mol-ecule and 71.53 (8), 28.85 (8) and 41.87 (8)°, respectively, in the other. The crystal structure features C-H⋯π inter-actions and weak π-π stacking inter-actions [centroid-centroid distances = 3.6937 (10) and 4.0232 (10) Å] between the chloro-phenyl rings, which form a three-dimensional supramolecular structure.

Project description:In the title compound, C(9)H(9)ClN(2), a substituted imidazoline, the six- and five-membered rings are twisted from each other, making a dihedral angle of 17.07?(5)°.
