The molecular structure of (I), drawn with 30% probability displacement ellipsoids.
In the title compound, C 10 H 16 O 5 , the carboxylate group at the C-2 position is axial, but that at C-5 is equatorial. These carboxylate groups form hydrogen-bonded rings [average OÁ Á ÁO H distance = 2.64 (1) A Ê ] across the inversion centers at ( 1 2 , 0, 0) and ( 1 2 , 1 2 , 1 2 ), respective
In the title molecule, C 18 H 18 O 5 , the cyclohexene ring adopts an envelope conformation. The dihedral angle between the two furan rings is 65.9 (1) . In the crystal structure, the carboxyl groups of inversion-related moleules are involved in the formation of dimers through OÐHÁ Á ÁO hydrogen bon
