%X 2-(3-(4-acetoxyphenyl)propanoyl)benzene-1,3,5-triyl triacetate (<b>1</b>), C<sub>25</sub>H<sub>22</sub>O<sub>9</sub> and 4-(3-(4-acetoxyphenyl)propanoyl)-5-hydroxy-1,3-phenylene diacetate (<b>2</b>), C<sub>21</sub>H<sub>20</sub>O<sub>8</sub> were formed via esterification of phloretin and acetic anhydride, respectively. Their structures all reveal three-dimensional framework structures. In (<b>1</b>), the molecule, which contains two intramolecular O&ctdot;O interactions, is existed as dimer that forms classic cyclic R<sup>2</sup><sub>2</sub> (9) C-H&ctdot;O hydrogen bonding interactions. The molecules are linked by a combination of C-H&ctdot;O and C-H&ctdot;¦Ð(arene) hydrogen bonds. It is interesting that two molecules of the dimer occur different intermolecular interactions. In (<b>2</b>), several weak C-H&ctdot;O interactions of the types Caryl-H&ctdot;O, C<sub>sp</sub><sup>3</sup>-H&ctdot;O and intramolecular hydrogen bond O-H&ctdot;O are present. Both molecules give cyclic R<sup>2</sup><sub>2</sub> (4) motif. These hydrogen bonds and interactions appear to play an important role in controlling the molecular conformation.
