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—HN hydrogen bonds lead to dimer formation, whereas BrCl short contacts [3.4966 (11) Å] form infinite chains along the a-axis direction. Further, the C—HO, C—Hπ 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—HO and C—HF hydrogen bonds stabilize the three-dimensional supramolecular architecture. Weak C—Hπ and π–π interactions [centroid–centroid distance = 3.877 (3) Å] lead to a criss-cross molecular packing along the c axis.
