چکیده
The β-lactam ring of the title compound, C(35)H(23)NO(2), 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 intra-molecular C-H⋯O and C-H⋯N contacts and mol-ecules are also linked by C-H⋯π inter-actions.
