4-(9-Anthr-yl)-1-(4-methoxy-phen-yl)spiro-[azetidin-3,9'-xanthen]-2-one.

ABSTRACT: In the title mol-ecule, C(36)H(25)NO(3), the β-lactam ring is essentially planar, with a dihedral angle of 3.3 (2)° between the two separate three-atom N/C/C planes. The β-lactam ring makes dihedral angles of 28.45 (14), 87.4 (1) and 51.8 (1)° with the mean planes of the benzene, xanthene and anthracene ring systems, respectively. In addition to a weak intra-molecular C-H⋯N hydrogen bond, the crystal structure is stabilized by two weak inter-molecular C-H⋯O hydrogen bonds.
