In the title compound, C(39)H(25)NO(2)center dot 0.5C(6)H(14), the beta-lactam ring is nearly planar [maximum deviation of 0.012 (2) angstrom from the mean plane] and makes dihedral angles of 36.41 (13), 88.87 (13) and 54.16 (12)degrees, respectively, with the naphthalene, xanthene and anthracene ring systems. The molecular conformation is stabilized by intramolecular C-H center dot center dot center dot O and C-H center dot center dot center dot N contacts. The complete solvent molecule is generated by inversion. In the crystal structure, molecules are linked to each other by C-H center dot center dot center dot pi interactions.
