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

What is it about?

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, [pi]-[pi] 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.
