The asymmetric unit of the title compound, C(22)H(20)N(2), contains two crystallographically independent mol-ecules in which the planar benzimidazole ring systems are oriented with respect to the adjacent tolyl rings at dihedral angles of 47.08 (8)/76.85 (8) and 39.52 (9)/87.49 (9)°, while the dihedral angles between the tolyl rings are 73.99 (3) and 81.51 (9)°. In the crystal structure, pairs of inter-molecular C-H⋯N inter-actions link one of the asymmetric mol-ecules into centrosymmetric dimers through R(2) (2)(8) ring motifs.
标题化合物C(22)H(20)N(2)的不对称单元包含两个晶体学独立分子，其中平面苯并咪唑环系相对于相邻甲苯基环的二面角分别为47.08 (8)/76.85 (8)°和39.52 (9)/87.49 (9)°，而甲苯基环之间的二面角为73.99 (3)°和81.51 (9)°。在晶体结构中，分子间C—H⋯N相互作用对通过R(2) (2)(8)环模式将其中一个不对称分子连接成中心对称二聚体。
