  • Title: Polymorphs and Versatile Solvates of 7-Hydroxyisoflavone.
    Author: Gong N, Zhang G, Jin G, Du G, Lu Y.
    Journal: J Pharm Sci; 2016 Apr; 105(4):1387-97. PubMed ID: 26935882.
    Abstract:
    7-hydroxyisoflavone has been crystallized, identified, and characterized as 2 solvent-free conformational polymorphs and 5 solvates, which differ from each other in the mode of packing and in molecular conformation. All the 7 crystal structures were previously unreported. The conformational polymorphs and solvates were compared by Hirshfeld surface and fingerprint plot analysis and were spectroscopically characterized by powder X-ray diffraction, differential scanning calorimetry, and thermal gravimetric analysis. Hydrogen bond played an important role in the formation of polymorphs. From this study, we can predict that more solvates could be cultivated in other polarity solvents such as isopropanol or 2-butanol at appropriate conditions.
