N-(4-Chlorophenyl)-1,8-naphthalimide

Abstract

In the title compound, C18H10ClNO2, the naphthalimide ring system is almost planar, the rings forming dihedral angles of 2.05 (3), 2.26 (3) and 0.80 (3)°. The attached benzene ring of the 4-chlorophenyl substituent is inclined to the mean plane of the naphthalimide ring system by 75.77 (11)°. In the crystal structure, symmetry-related molecules are linked by C—H...O interactions. There are also weak π–π contacts between the naphthalimide rings [centroid–centroid distance = 3.732 (3) Å].
