There are two independent mol-ecules in the asymmetric unit of the title compound, C(15)H(10)ClNO(2), which differ in the dihedral angles between the mean planes of the phenyl ring and the 4-chloro-indoline-2,3-dione ring system [59.48 (9) and 79.0 (1)°]. In the crystal, mol-ecules are linked through C-H⋯O hydrogen bonds, forming polymeric chains in [100].
