1-[2-(2,5-Dichlorobenzyloxy)-2-phenyl-ethyl]-1H-benzotriazole

In the title mol-ecule, C21H17Cl2N 3O, the benzotriazole ring is oriented at dihedral angles of 48.72 (6) and 62.94 (5)°, respectively, to the phenyl and benzene rings and the dihedral angle between the phenyl and benzene rings is 88.95 (6)°. In the crystal, weak C - H?N hydrogen bonds link the mol-ecules into chains. ?-? contacts between the triazole and benzene rings [centroid-centroid distance = 3.678 (1) Å] and a weak C - H?? interaction are also observed
