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

In the title compound, C 10 H 9 ClN 4 OS, an intramolecular N—H...O hydrogen-bonding interaction and an N—H...N interaction generate ring motifs [graph sets S (6) and S (5), respectively]. In the crystal, molecules form a chain through N—H...O hydrogen bonds, and these are extended by N—H...S hydrogen-bonding interactions into an infinite three-dimensional network. The crystal structure also exhibits weak C—H...π interactions.
