چکیده
The asymmetric unit of the title compound, C(21)H(17)Cl(2)N(3)O, contains two crystallographically independent mol-ecules with similar conformations. The benzotriazole ring is oriented at dihedral angles of 30.61 (5) and 43.36 (5)°, respectively, to the phenyl and dichloro-phenyl rings in one mol-ecule, and 32.25 (5) and 41.04 (5)° in the other. The dihedral angles between the phenyl and dichloro-phenyl rings are 66.38 (7) and 66.14 (6)° in the two mol-ecules. An intra-molecular O-H⋯N hydrogen bond links the benzotriazole ring and phenyl-propanol unit in each mol-ecule. In the crystal, weak inter-molecular C-H⋯N hydrogen bonds link the mol-ecules into chains along the a axis. π-π stacking between the dichloro-phenyl rings [centroid-centroid distances = 3.809 (1) and 3.735 (1) Å] may further stabilize the crystal structure.
