Abstract
In the title compound, C21H19ClO3, the two cyclohexenone rings adopt half-chair conformations, whereas the pyran ring adopts a boat conformation. The 4-chlorophenyl ring is almost perpendicular to the plane through the four C atoms of the pyran ring [dihedral angle = 87.97 (6) ]. In the crystal, weak C—H O hydrogen bonds link the molecules into a chain parallel to the a-axis.
