β¦ Synopsis
The title compound, C 15 H 8 Br 2 Cl 3 FO, crystallizes with two independent molecules in the asymmetric unit. The dihedral angle between the two benzene rings is 58.0 (2) in one molecule and 52.0 (2) in the other. A C-HΓ Γ ΓCl intramolecular interaction is observed. The crystal packing is stabilized by van der Waals interactions.

The title compound, C 15 H 7 BrCl 3 FO, crystallizes with two molecules in the asymmetric unit. The molecular conformation is stabilized by C-HΓ Γ ΓBr intramolecular interactions.
In the title compound, C 15 H 10 Br 2 ClN 3 O, the benzotriazole mean plane makes a dihedral angle of 57.09 (1) with the other benzene ring. In the crystal structure, the packing is stabilized by C-HΓ Γ Γ interactions, together with close BrΓ Γ ΓN and BrΓ Γ ΓBr interactions [3.292 (3), 3.054 (3), 3.
In the title molecule, C~16~H~11~Br~3~Cl~2~O~2~, the chain Br atoms are in __trans__ positions [BrβCβCβBr torsion angle is 179.0β (2)Β°]. The two benzene rings make a dihedral angle of 39.54β (15)Β°.
