In the title compound, C17H11Cl6NO4, the configuration of the cyclo-alkene skeleton is endo,cis. The benzene ring is twisted by 58.94 (8)° from the attached pyrrolidine ring. Two carbonyl groups play a key role in the crystal packing. A short inter-molecular C⋯O distance of 3.017 (3) Å reveals that one carbonyl group is involved in dipole-dipole inter-actions, which link two adjacent enanti-omers into an inversion dimer. Another carbonyl group provides an acceptor for the weak inter-molecular C-H⋯O hydrogen bonds which link these dimers into layers parallel to (011).
