1-[2-(1H-Benzimidazol-2-yl)eth­yl]-1H-1,2,3-benzotriazole

In the title compound, C(15)H(13)N(5), the N-containing heterocycles are linked by an ethyl­ene spacer in a gauche conformation, the N—C—C—C torsion angle along the linker being 60.1 (3)°. The dihedral angle between the terminal benzotriazole and benzimidazole rings is 39.02 (6)°. In the crystal, adjacent mol­ecules are connected by N—H⋯N hydrogen bonds, forming an infinite chain along the c axis. π–π stacking inter­actions [centroid–centroid distance = 3.8772 (7) Å] between the benzotriazole rings of neighbouring chains extend these chains into a supra­molecular sheet in the bc plane. Weak inter­molecular C—H⋯N inter­actions further stabilize the crystal structure.
