title: (E)-3-(2,6-Dichloro-benzyl-idene)indolin-2-one.
abstract: There are two independent mol-ecules in the asymmetric unit of the title compound, C(15)H(9)Cl(2)NO. The dihedral angles between the oxindolyl and dichloro-phenyl rings are essentially identical for the two independent mol-ecules [63.4 (1) and 63.2 (1)°]. Dimers linked by amide-carbonyl N-H⋯O hydrogen bonds are formed from each symmetry-independent mol-ecule and the respective symmetry equivalent created by inversion.
