ABSTRACT
In the title di-hydro-dioxin, C31H28O5, the dioxane ring has a chair conformation, whereas each of the pyran and dioxine rings has an envelope conformation with methyl-ene and quaternary C atoms, respectively, being the flap atoms. The phenyl rings are cis and form a dihedral angle of 82.11â
(10)°. The molecular structure is stabilized by C-Hâ¯O contacts. In the crystal packing, supra-molecular layers parallel to (101) are sustained by C-Hâ¯π inter-actions.
