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

Abstract

In the title compound, C 15H 13N 5, the N-containing heterocycles are linked by an ethyl-ene 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 supra-molecular sheet in the bc plane. Weak intermolecular C-H⋯N interactions further stabilize the crystal structure.
