Özet

In the title molecule, C36H25NO3, the beta-lactam ring is essentially planar, with a dihedral angle of 3.3 (2)degrees between the two separate three-atom N/C/C planes. The beta-lactam ring makes dihedral angles of 28.45 (14), 87.4 (1) and 51.8 (1)degrees with the mean planes of the benzene, xanthene and anthracene ring systems, respectively. In addition to a weak intramolecular C-H center dot center dot center dot N hydrogen bond, the crystal structure is stabilized by two weak intermolecular C-H center dot center dot center dot O hydrogen bonds.
