4-(9-Anthr-yl)-1-Phenylspiro-[Azetidine-3,9'-Xanthen]-2-one

Abstract

The Β-lactam ring of the title compound, C35NH 23NO2, 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.
