1-(4-Bromo-benz-yl)-2-(4-bromo-phen-yl)-1H-benzimidazole.

ABSTRACT: There are two mol-ecules in the asymmetric unit of the title compound, C20H14Br2N2. In the first, the dihedral angles between the mean plane of the benzimidazole group and those of the 4-bromo-benzyl and 4-chloro-phenyl groups are 50.72?(17) and 71.29?(16)°, respectively, while the corresponding angles in the second mol-ecule are 42.09?(16) and 89.05?(17)°. The 4-bromo-benzyl and 4-bromo-phenyl groups make an angle of 68.1?(2) and 85.1?(21)° with each other in the two mol-ecules. In the crystal, weak C-H?N and C-H?Br hydrogen bonds link the mol-ecules along the c-axis direction. Br?Br inter-actions [3.5733?(9)Å] are also observed.

Project description:The title compound, C(22)H(20)N(2), crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The benzimidazole units are almost planar [maximum deviations = 0.0161 (8) Å for A and 0.0276 (8) Å for B]. The dihedral angles between the benzimidazole unit and the benzene rings of the 4-methyl-benzyl and 4-methyl-phenyl groups are 76.64 (3) and 46.87 (4)°, respectively, in mol-ecule A. The corresponding values in mol-ecule B are 86.31 (2) and 39.14 (4)°. The dihedral angles between the planes of the two benzene rings are 73.73 (3) and 80.69 (4)° in mol-ecules A and B, respectively. Pairs of weak inter-molecular C-H⋯N hydrogen bonds link B mol-ecules, forming centrosymmetric dimers with R(2) (2)(8) ring motifs. There are no significant corresponding inter-actions involving the A mol-ecules.
