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

In the title compound, C(15)H(11)BrN(4)OS, 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.
