title: 3-(4-Fluoro-benzyl-idene)-1,5-dioxa-spiro-[5.5]undecane-2,4-dione.
abstract: In the title mol-ecule, C(16)H(15)FO(4), the fused 1,3-dioxane and cyclo-hexane rings exhibit a bath and a chair conformation, respectively. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
