摘要

The crystal structures of 2',4'-dihydroxy-3-methoxy-alpha,beta-di-hydrochalcone, C_(16)H_(16)O_4, and 2',4-dihydroxy-alpha,beta-dihydro-chalcone, C_(15)H_(14)O_3, have been determined. In both compounds, the structure consists of two nearly planar six-membered aromatic rings connected by a propanal chain, which is bent in the methoxy compound and almost straight in the other compound. In the crystal structures, the molecular units of both compounds are linked by O-H...O hydrogen bonds to form infinite one-dimensional chains.Hydrogen bonds and C-H...O contacts in the crystal structures were studied by topological analysis of charge density based on Hartree-Fock calculations. Almost all of the investigated C- H...O contacts should be characterized as weak hydrogen bonds.
