Crystal structure of 4,5,6,7,8,8-hexachloro-2-(3,4-dimethoxyphenethyl)-3a, 4,7,7a-tetrahydro-1H-4,7-methanoisoindole-1,3(2H)-dione [+solvent]

In the title compound, C19H15Cl6NO4 [+solvent], the sixq-membered ring of the norbornene moiety adopts a boat conformation and the two fiveq-membered rings have envelope conformations. The pyrrolidine ring makes a dihedral angle of 14.83 (12)degrees with the 3,4-dimethoxyphenyl ring, which are attached to each other by an extended N-CH2-CH2-C-ar bridge. In the crystal, the structure features C-H center dot center dot center dot O intermolecular hydrogen bonds, an offset pi-pi interaction [ intercentroid distance = 3.564 (1) angstrom] and a C-Cl center dot center dot center dot pi interaction. The contribution of some disordered solvent to the scattering was removed using the SQUEEZE routine [Spek (2015). Acta Cryst. C71, 9-18] of PLATON. The solvent contribution was not included in the reported molecular weight and density.
