Crystallization of the hexa-host hexakis(4-cyanophenyloxy)benzene from various solvents yields inclusion compounds which were characterized by single crystal X-ray diffraction, powder X-ray diffraction, and thermal analysis. Although the ababab conformation of the hexa-host molecule is most commonly encountered in the crystal structures, the two unusual conformations aaabbb and aaabab were also observed in this study. Desolvation of all of these inclusion compounds produces the same apohost phase, as confirmed by powder X-ray diffraction.
