In the title compound, C21H13BrClNO2S, the dihedral angle between the planes of the benzothia­zole and chloro­phenyl­methanone groups is 71.34 (6)°. In the crystal, weak C—H...N hydrogen bonds lead to dimer formation, whereas Br...Cl short contacts [3.4966 (11) Å] form infinite chains along the a-axis direction. Further, the C—H...O, C—H...π and π–π [centroid–centroid distance = 3.865 (2) Å] inter­actions stabilize the three-dimensional network.

The asymmetric unit of the title compound, C21H13ClFNO2S, contains two independent mol­ecules with similar conformations. In the mol­ecules, the thia­zole ring is essentially planar [maximum atomic deviations = 0.014 (4) and 0.023 (5) Å] and is oriented with respect to the fluoro­phenyl ring and chloro­phenyl rings at 9.96 (18) and 70.39 (18)° in one mol­ecule and at 7.50 (18) and 68.43 (18)° in the other; the dihedral angles between the fluoro­phenyl and chloro­phenyl rings are 64.9 (2) and 64.6 (2)°, respectively. Inter­molecular C—H...O and C—H...F hydrogen bonds stabilize the three-dimensional supra­molecular architecture. Weak C—H...π and π–π inter­actions [centroid–centroid distance = 3.877 (3) Å] lead to a criss-cross mol­ecular packing along the c axis.
