title: 2-(1H-Benzotriazol-1-yl)-1-(4-bromo-benzo-yl)ethyl 2-chloro-benzoate.
abstract: 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 bromo-phenyl and chloro-phenyl rings, respectively; the angle between the latter two rings is 69.26 (1)°. In the crystal structure, mol-ecules are linked into chains by inter-molecular C-H⋯O hydrogen bonds. The crystal packing is further stabilized by π-π (with a centroid-centroid distance of 3.764 Å) and C-H⋯π inter-actions.
