The title molecule, C9H6ClNO2, is essentially planar: the maximum deviation from the mean plane of the indoline ring is 0.020 (2) Å and the substituents do not deviate by more than 0.053 (2) Å from this plane. C—HO hydrogen bonds help to consolidate the crystal structure.

There are two independent molecules in the asymmetric unit of the title compound, C15H10ClNO2, which differ in the dihedral angles between the mean planes of the phenyl ring and the 4-chloroindoline-2,3-dione ring system [59.48 (9) and 79.0 (1)°]. In the crystal, molecules are linked through C—HO hydrogen bonds, forming polymeric chains in [100].
