Crystal structure of 1,7,8,9-tetra­chloro-4-(3,5-di­chloro­benz­yl)-10,10-dimeth­oxy-4-aza­tri­cyclo­[5.2.1.02,6]dec-8-ene-3,5-dione

摘要

In the title compound, C17H11Cl6NO4, the configuration of the cyclo­alkene 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 inter­molecular C⋯O distance of 3.017 (3) Å reveals that one carbonyl group is involved in dipole–dipole inter­actions, which link two adjacent enanti­omers into an inversion dimer. Another carbonyl group provides an acceptor for the weak inter­molecular C—H⋯O hydrogen bonds which link these dimers into layers parallel to (011).
