The molecule of the title compound, C12H9Br2NO2S, is U shaped with the central C—S—N—C segment having a torsion angle of 63.2 (4)°. Further, the dihedral angle between the benzene rings is 38.5 (2)°. The crystal structure features strong N—H...O hydrogen bonds that form infinite [100] C(4) chains. Molecules in adjacent chains are interlinked via C—H...O interactions which run along the b axis, forming C(7) chains. This results in a two-dimensional network in the ab plane; adjacent networks are connected by short Br...Br contacts [3.5092 (8) Å] propagating along the diagonal of the ac plane, so that a three-dimensional supramolecular architecture ensues.
