Abstract: In the title compound, C21H13Cl2NO2S, the benzothiazole ring makes dihedral angles of 0.94 (1) and 70.65 (5)° with the 4-chlorophenylmethanone unit and the 5-chlorophenyl ring, respectively. The dihedral angle between the 4-chlorophenylmethanone unit and the 5-chlorophenyl ring is 66.20 (5)°. The crystal structure consists of dimeric units generated by C-HN hydrogen bonds, further linked by C-HO and C-H interactions, leading to a three-dimensional network.
