title: 3,3-Dichloro-1-(chloro-meth-yl)indolin-2-one.
abstract: In the title compound, C(9)H(6)Cl(3)NO, the pyrrole ring is almost coplanar with the benzene ring [dihedral angle = 1.90 (9)°], while the Cl-C-N-C torsion angle is 98.78 (17)°. In the crystal, pairs of mol-ecules are inter-connected by pairs of Cl⋯Cl inter-actions [3.564 (5) Å], forming dimers, which are further peripherally connected through inter-molecular C-H⋯O=C and π-π inter-actions [centroid-centroid distances = 4.134 (7), 4.134 (6) and 4.238 (7) Å], forming a two-dimensional network.
