Abstract
In the title compound, C15H12N4OS, the dihedral angle between the nine-membered indolin-2-one ring system and the phenyl ring is 2.72 (7)°. Intramolecular cyclic N—H⋯O and C—H⋯S hydrogen-bonding interactions [graph set S(6)] are present, as are weak N—H⋯N interactions [graph set S(5)]. In the crystal, molecules form centrosymmetric cyclic dimers through pairs of N—H⋯O hydrogen bonds [graph set R 2 2(8)] and these are extended by C—H⋯S interactions. The crystal structure also features weak C—H⋯π interactions.
