Abstract

Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.004 Å; R factor = 0.041; wR factor = 0.103; data-to-parameter ratio = 14.7.In the title compound, C 22 H 15 BrClN 3 O 3 , the benzotriazole ring system makes dihedral angles of 2.43 (1) and 71.51 (1) with the bromophenyl and chlorophenyl rings, respectively; the angle between the latter two rings is 69.26 (1) . In the crystal structure, molecules are linked into chains by intermolecular C-HÁ Á ÁO hydrogen bonds. The crystal packing is further stabilized by -(with a centroid-centroid distance of 3.764 Å ) and C-HÁ Á Á interactions.
