Abstract

Crystallography Physical Sciences Science & Technology
In the title compound, C21H22O5, the mean planes of the pyran and dimethoxyphenyl rings are nearly perpendicular to one another, with the dihedral angle between them being 88.21 (8)degrees. The pyran ring adopts a boat conformation whereas the two fused cyclohexane rings adopt envelope conformations. In the crystal, molecules are linked into a three-dimensional network by intermolecular C-H...O hydrogen bonds.
