(Z)-2-(5-Methyl-2-oxoindolin-3-ylidene)-N-phenylhydrazinecarbothioamide

Abstract

In the title compound, C16H14N4OS, the dihedral angle between the nine-membered 5-methylindolin-2-one ring system and the benzene ring is 10.21 (7)°. Intramolecular cyclic N—H...O and C—H...S hydrogen-bonding interactions [graph set S(6)] are present within the N—N—C—N chain between the ring systems. In the crystal, molecules form centrosymmetric cyclic dimers through pairs of N—H...O hydrogen bonds [graph set R22(8)].
