In the title compound, C24H17Cl2NO2, the succinimide ring adopts a half-cha
ir conformation, and the attached phenyl ring is twisted by an angle of 55.
0 (1)degrees with respect to the succinimide mean plane. The cyclobutane ri
ng is non-planar and is substituted by two phenyl rings oriented at angles
of 38.3 (1) and 75.7 (1)degrees to the cyclobutane mean plane. The dihedral
angle between the succinimide and cyclobutane rings is 64.8 (1)degrees.
