Abstract: In the title compound, C39H25NO2·0.5C6H14, the -lactam ring is nearly planar [maximum deviation of 0.012 (2) Å from the mean plane] and makes dihedral angles of 36.41 (13), 88.87 (13) and 54.16 (12)°, respectively, with the naphthalene, xanthene and anthracene ring systems. The molecular conformation is stabilized by intramolecular C-HO and C-HN contacts. The complete solvent molecule is generated by inversion. In the crystal structure, molecules are linked to each other by C-H interactions.
