Abstract: The -lactam ring of the title compound, C₃₅H₂₃NO₂, is nearly planar with a maximum deviation of 0.003 (3) Å from the mean plane. It makes dihedral angles of 17.4 (2), 85.22 (17) and 65.39 (16)°, respectively, with the phenyl, xanthene and anthracene ring systems. In the crystal structure, there are intramolecular C-HO and C-HN contacts and molecules are also linked by C-H interactions.
