摘　　要：2-(3-(4-acetoxyphenyl)propanoyl)benzene-1,3,5-triyl triacetate (1), C₂₅H₂₂O₉ and 4-(3-(4-acetoxyphenyl)propanoyl)-5-hydroxy-1,3-phenylene diacetate (2), C₂₁H₂₀O₈ were formed via esterification of phloretin and acetic anhydride, respectively. Their structures all reveal three-dimensional framework structures. In (1), the molecule, which contains two intramolecular O⋯O interactions, is existed as dimer that forms classic cyclic R²₂ (9) C-H⋯O hydrogen bonding interactions. The molecules are linked by a combination of C-H⋯O and C-H⋯π(arene) hydrogen bonds. It is interesting that two molecules of the dimer occur different intermolecular interactions. In (2), several weak C-H⋯O interactions of the types Caryl-H⋯O, C_sp³-H⋯O and intramolecular hydrogen bond O-H⋯O are present. Both molecules give cyclic R²₂ (4) motif. These hydrogen bonds and interactions appear to play an important role in controlling the molecular conformation.2-(3-(4-acetoxyphenyl)propanoyl)benzene-1,3,5-triyl triacetate (1), C₂₅H₂₂O₉ and 4-(3-(4-acetoxyphenyl)propanoyl)-5-hydroxy-1,3-phenylene diacetate (2), C₂₁H₂₀O₈ were formed via esterification of phloretin and acetic anhydride, respectively.
