Abstract: In the title compound, C15H11BrN4OS, the least-squares plane through the 5-bromoisatin fragment forms a dihedral angle of 13.63 (14)° with the phenyl ring. The molecular conformation features intramolecular N-HN and N-HO hydrogen bonds. In the crystal, molecules are connected via pairs of N-HO interactions into centrosymmetric dimers. Additionally, - stacking interactions link molecules into chains parallel to the a axis with short CC distances being observed between the phenyl and thiocarbonyl [3.236 (8) Å] groups and between the thiocarbonyl and carbonyl [3.351 (4) Å] groups of stacked molecules.
