1-[2-(2,5-Dichloro-benz-yloxy)-2-phenyl-eth-yl]-1H-benzotriazole.

In the title mol-ecule, C(21)H(17)Cl(2)N(3)O, 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. π-π contacts between the triazole and benzene rings [centroid-centroid distance = 3.678 (1) Å] and a weak C-H⋯π inter-action are also observed.
