Abstract

The asymmetric unit of the title compound, C21H17Cl2N3O, contains two crystallographically independent molecules with similar conformations. The benzotriazole ring is oriented at dihedral angles of 30.61 (5) and 43.36 (5)degrees, respectively, to the phenyl and dichlorophenyl rings in one molecule, and 32.25 (5) and 41.04 (5)degrees in the other. The dihedral angles between the phenyl and dichlorophenyl rings are 66.38 (7) and 66.14 (6)degrees in the two molecules. An intramolecular O-H center dot center dot center dot N hydrogen bond links the benzotriazole ring and phenylpropanol unit in each molecule. In the crystal, weak intermolecular C-H center dot center dot center dot N hydrogen bonds link the molecules into chains along the a axis. pi-pi stacking between the dichlorophenyl rings [centroid-centroid distances = 3.809 (1) and 3.735 (1) angstrom] may further stabilize the crystal structure.
