Polymorphism of a Hexa-host: Isolation of Four Different Single-Crystal Phases by Melt Crystallization
A hexa-host compound yields at least four polymorphic forms from its melt phase. All four phases have been characterized using single-crystal X-ray diffraction; two of the phases were obtained by means of thermal stress, and the different forms exhibit conformational polymorphism.
