4-(9-Anthr-yl)-1-(1-naphth-yl)spiro-[azetidine-3,9'-xanthen]-2-one n-hexane hemisolvate
Abstract:
In the title compound, C(39)H(25)NO(2)·0.5C(6)H(14), 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.
