Abstract
The title molecule, C24H15NO4, crystallizes with two molecules in the asymmetric unit (Z′ = 2). For both molecules, the two amide groups are not coplanar, as the dihedral angles of the respective NCO groups are similar at 50.37 (14) and 51.22 (13)°. However, the orientations of the substituent phenyl rings with the central naphthalene system are significantly different for the two molecules; for one molecule, these dihedral angles are 80.29 (3) and 80.95 (4)°, while for the second molecule they are 86.63 (3) and 72.82 (4)°. The crystal packing shows the molecules to be linked by weak C—H⋯O interactions.
