5-Ferrocenyl-5-methyl­tetra­hydro­furan-2-one, the product of the Friedel–Crafts reaction of ferrocene with γ-methylene­butyrolactone

In the mol­ecular structure of 5-ferrocenyl-5-methyl­tetra­hydro­furan-2-one, [Fe(C₅H₅)(C₁₀H₁₁O₂)], the five-membered heterocyclic ring adopts a distorted envelope conformation. The ferrocenyl substituent is in an equatorial position with respect to this ring. In the crystal structure, there are close C—H...O and C—H...π inter­molecular contacts.
