Abstract

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.
