1,3-Bis[(1H-benzotriazol-1-yl)meth-yl]-2,3-dihydro-1H-benzimidazole.

In the title compound, C(21)H(18)N(8), the two (benzotriazol-1-yl)methyl groups are located in an anti position with respect to the benzimidazoline moiety. The dihedral angles between the benzotriazole ring systems and the central benzimidazoline moiety are 57.03†(4) and 81.01†(3)°. The crystal packing is stabilized by two C-H⋯π inter-actions.
