1-(4-Methyl­benz­yl)-2-(4-methyl­phen­yl)-1H-benzimidazole

摘要

The title compound, C22H20N2, crystallizes with two independent mol­ecules (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-methyl­benzyl and 4-methyl­phenyl groups are 76.64 (3) and 46.87 (4)°, respectively, in mol­ecule A. The corresponding values in mol­ecule 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 mol­ecules A and B, respectively. Pairs of weak inter­molecular C—H⋯N hydrogen bonds link B mol­ecules, forming centrosymmetric dimers with R 2 ²(8) ring motifs. There are no significant corresponding inter­actions involving the A mol­ecules.
