1,5-Di­chloro-3,6,6-tri­phenyl-3-aza­bi­cyclo­[3.2.0]­heptane-2,4-dione

In the title compound, C₂₄H₁₇Cl₂NO₂, the succin­imide ring adopts a half-chair conformation, and the attached phenyl ring is twisted by an angle of 55.0 (1)° with respect to the succin­imide mean plane. The cyclo­butane ring is non-planar and is substituted by two phenyl rings oriented at angles of 38.3 (1) and 75.7 (1)° to the cyclo­butane mean plane. The dihedral angle between the succin­imide and cyclo­butane rings is 64.8 (1)°.
