3,3-Dichloro-1-(chloromethyl)indolin-2-one

Abstract

In the title compound, C9H6Cl3NO, 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 molecules are interconnected by pairs of Cl...Cl interactions [3.564 (5) Å], forming dimers, which are further peripherally connected through intermolecular C—H...O=C and π–π interactions [centroid–centroid distances = 4.134 (7), 4.134 (6) and 4.238 (7) Å], forming a two-dimensional network.
