3-(4-Fluoro­benzyl­idene)-15-dioxa­spiro­5.5undecane-24-dione

摘要

In the title mol­ecule, C16H15FO4, the fused 1,3-dioxane and cyclo­hexane rings exhibit a bath and a chair conformation, respectively. In the crystal, weak inter­molecular C—H⋯O hydrogen bonds link the mol­ecules into centrosymmetric dimers.
