The attached benzene ring of the 4-chlorophenyl substituent is inclined to the mean plane of the naphthalimide ring system by 75.77 (11)¡ã. In the crystal structure, symmetry-related molecules are linked by C¡ªH...O interactions. There are also weak ¦Ð¨C¦Ð contacts between the naphthalimide rings [centroid¨Ccentroid distance = 3.732 (3) ]. %U http://scripts.iucr.org/cgi-bin/paper?S1600536809020777
