Abstract:
In the title compound, C(15)H(13)N(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 mol-ecules are connected by N-H⋯N hydrogen bonds, forming an infinite chain along the c axis. π-π stacking inter-actions [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 inter-molecular C-H⋯N inter-actions further stabilize the crystal structure.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
