2-(1H-Benzotriazol-1-yl)-3-(2,6-dichlorophenyl)-1-phenylpropan-1-ol

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