Crystal structure and Hirshfeld surface analysis of (3aR,4S,7S,7aS)-4,5,6,7,8,8-hexa-chloro-2-{6-[(3aR,4R,7R,7aS)-4,5,6,7,8,8-hexa-chloro-1,3-dioxo-1,3,3a,4,7,7a-hexa-hydro-2H-4,7-methano-isoindol-2-yl]hex-yl}-3a,4,7,7a-tetra-hydro-1H-4,7-methano-iso-indole-1,3(2H)-dione.

The mol­ecule of the title compound, C24H16Cl12N2O4, is generated by a crystallographic inversion centre at the midpoint of the central C—C bond. A kink in the mol­ecule is defined by a torsion angle of −169.86 (15)° about this central bond of the alkyl bridge. The pyrrolidine ring is essentially planar [max. deviation = 0.014 (1) A]. The cyclo­hexane ring has a boat conformation, while both cyclo­pentane rings adopt an envelope conformation. In the crystal structure, mol­ecules are linked by inter­molecular C—H⋯O, C—H⋯Cl and C—Cl⋯π inter­actions, and short inter­molecular Cl⋯O and Cl⋯Cl contacts, forming a three-dimensional network.
