Cis-3,3-Dimethyl-3,3a,4,5,6,6a-hexa-hydro-1H-cyclo-penta-[c]furan-1,6-dione.

ABSTRACT: The bicyclic mol-ecule of the title compound, C(9)H(12)O(3), contains two five-membered rings with different functional groups, viz. a ketone and an ester. Both rings assume an envelope conformation. The mean planes of these functional groups form a dihedral angle of 60.7?(1)°. The crystal structure exhibits weak inter-molecular C-H?O inter-actions, which link the mol-ecules into zigzag chains extended in the [010] direction. The unit cell contains a racemic mixture of enanti-omers.
