4-Chloro-1-methylindoline-2,3-dione
Abstract
The title molecule, C9H6ClNO2, is essentially planar; the maximum deviation of the indoline ring system is 0.027 (3) Å and the substituents do not deviate by more than 0.075 (2) Å from this plane. Intermolecular C—H...O hydrogen bonds consolidate the crystal structure.
