4-(9-Anthryl)-1-(1-Naphthyl)spiro[Azetidine-3,9'-Xanthen]-2-one n-Hexane Hemisolvate

Abstract

In the title compound, C39H25NO2·0.5C6H14, the Β-lactam ring is nearly planar [maximum deviation of 0.012 (2) Å from the mean plane] and makes dihedral angles of 36.41 (13), 88.87 (13) and 54.16 (12)°, respectively, with the naphthalene, xanthene and anthracene ring systems. The mol-ecular conformation is stabilized by intra-molecular C - H⋯O and C - H⋯N contacts. The complete solvent mol-ecule is generated by inversion. In the crystal structure, mol-ecules are linked to each other by C - H⋯π inter-actions. © 2008.
