1-(5-Bromo-2-oxoindolin-3-ylidene)-4-phenylthiosemicarbazide

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—H...N and N—H...O hydrogen bonds. In the crystal, molecules are connected via pairs of N—H...O interactions into centrosymmetric dimers. Additionally, π–π stacking interactions link molecules into chains parallel to the a axis with short C...C 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.
