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.

Crystallization of hexakis(4-cyanophenyloxy)benzene from a mixture of two different solvents produces two different solvates concomitantly, which were characterized by X-ray diffraction, thermal analysis and NMR spectroscopy.
