9-[(E)-2-(4-Chlorophenyl)ethenyl]-3,3,6,6-tetramethyl-2,3,4,5,6,7,8,9-octahydro-1H-xanthene-1,8-dione
In the title compound, C25H27ClO3, each of the cyclohexenone rings adopts an envelope conformation, whereas the six-membered pyran ring adopts a flattened boat conformation, with the O and methine C atoms deviating from the plane of the other four atoms. The C=C double bond is in the trans conforma...

| description |
In the title compound, C25H27ClO3, each of the cyclohexenone rings adopts an envelope conformation, whereas the six-membered pyran ring adopts a flattened boat conformation, with the O and methine C atoms deviating from the plane of the other four atoms. The C=C double bond is in the trans conformation. In the crystal, weak C—H⋯O hydrogen bonds link the molecules into chains running parallel to the b axis. |
