The title compounds, C<sub>9</sub>H<sub>12</sub>O<sub>6</sub> and C<sub>10</sub>H<sub>14</sub>O<sub>6</sub>, were formed by careful hydrolysis of the corresponding diethyl esters. Their single crystals were grown from an ethyl acetate/hexane mixture. Crystals of both compounds have monoclinic (<i>P</i>2<sub>1</sub>) symmetry with a single mol-ecule in the asymmetric unit. Both crystal structures are very similar and display four -CO-OH⋯O=C(OH)- hydrogen bonds, forming a two-dimensional double-la ...[more]
