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

Abstract

In the title compound, C15H11ClN4OS, the dihedral angle between the nine-membered 5-chloroindolin-2-one ring system and the benzene ring is 10.00 (6)°. Intramolecular cyclic N—H...O and C—H...S hydrogen-bonding interactions [graph set S(6)] are present in the N—N—C—N chain between the ring systems. In the crystal, molecules form centrosymmetric cyclic dimers through intermolecular N—H...O hydrogen bonds [graph-set R22(8)] and are extended by C—H...Cl interactions into infinite chains which propagate along [100].
