摘要：
This study investigates the relationships between the supramolecular structure and the solubility and melting point of six multicomponent crystals involving fumaric acid (FUM series) and adipic acid (ADI series). The crystals were prepared by solvent evaporation and fully characterised by thermal and diffraction techniques. In each series the melting points of the multicomponent crystals are lower than the relevant carboxylic acid and they show partial correlation with their aqueous solubilities. With the aid of Hirshfeld surface analysis, the relationships between solubility, melting point and the supramolecular structure are discussed.
