چکیده
The overall conformation of the title mol-ecule, C(14)H(11)BrO(3)S, is L-shaped, as seen in the value of the dihedral angle formed between the terminal benzene rings of 75.44 (13)°. The presence of C-H⋯O inter-actions leads to the formation of linear supra-molecular chains along the a-axis direction in the crystal structure. These are connected into supra-molecular arrays in the ab plane via C-H⋯π contacts.

In the title mol-ecule, C(15)H(10)BrNO(3)S(2), the dihedral angle between the benzothia-zole ring system and the benzene ring is 67.57 (12)°. The crystal structure is stabilized by weak inter-molecular C-H⋯O inter-actions. In addition, there is an inter-molecular Br⋯C [3.379 (3) Å] contact which is shorter than the sum of the van der Waals radii of these atoms.
