Crystal structure of 1,7,8,9-tetra-chloro-4-(2-fluoro-benz-yl)-10,10-dimeth-oxy-4-aza-tri-cyclo-[5.2.1.0(2,6)]dec-8-ene-3,5-dione.

In the title compound, C17H12Cl4FNO4, the configuration of the cyclo-alkene skeleton is endo,cis. The benzene ring is twisted by 71.01 (11)° from the attached pyrrolidine ring. In the crystal, one of the methine groups of the fused-ring system forms a weak C-H⋯O hydrogen bond. The other methine groups participates in a C-H⋯F inter-action to the same adjacent mol-ecule. Together, these generate [010] chains.
