In the title compound, C(17)H(11)Cl(6)NO(2), the six-membered ring of the norbornene moiety adopts a boat conformation whereas the two five-membered rings adopt envelope conformations. The phenyl ring and the ring of the succinimide moiety are almost coplanar [dihedral angle = 7.44 (14)°]. The crystal packing is stabilized by a weak inter-molecular C-H⋯O hydrogen bond.
