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, C(19)H(15)Cl(6)NO(4) [+solvent], the six-membered ring of the norbornene moiety adopts a boat conformation and the two five-membered rings have envelope conformations. The pyrrolidine ring makes a dihedral angle of 14.83 (12)° with the 3,4-di­meth­oxy­phenyl ring, which are attached to each other by an extended N—CH(2)—CH(2)—C(ar) bridge. In the crystal, the structure features C—H⋯O inter­molecular hydrogen bonds, an offset π–π inter­action [inter­centroid distance = 3.564 (1) Å] and a C—Cl⋯π 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.
