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...

Zusammenfassung: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.
