4-(9-Anthryl)-1-phenylspiro[azetidine-3,9 '-xanthen]-2-one

Abstract

The beta-lactam ring of the title compound, C35H23NO2, is nearly planar with a maximum deviation of 0.003 (3) angstrom from the mean plane. It makes dihedral angles of 17.4 (2), 85.22 (17) and 65.39 (16)degrees, respectively, with the phenyl, xanthene and anthracene ring systems. In the crystal structure, there are intramolecular C-H center dot center dot center dot O and C-H center dot center dot center dot N contacts and molecules are also linked by C-H center dot center dot center dot pi interactions.
