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
