2-Phenyl­selanyl-3,5-methano-2H-cyclo­penta­[b]­furan-2-one

The title compound, C₁₄H₁₄O₂Se, crystallizes as separate neutral mol­ecules each consisting of one norbornane moiety bridged through aa Se atom to a phenyl group and covalently bonded to both the C and O atoms of a carboxyl­ate group forming a five-membered ring. It is a useful intermediate in the synthesis of larger organometallic complexes. One mol­ecule of the title compound constitutes the asymmetric unit. The packing of mol­ecules in well defined layers results in a number of C—H...Se `agostic' interactions and weak C—H...O=C hydrogen bonds.
