Crystal structure of mono[3-(2-imidazolylthio)]-altro-beta-cyclodextrin: elliptical distortion of the cavity and unique 'Yin-Yang' stacking.
The title compound is elliptically distorted due to the unusual 1C4 geometry of the altrose portion. In packing, a unique fourfold helical structure is elaborated with head-to-head dimers as the repeating motif. The imidazolyl moieties mutually reside on each other's cavities thereby resembling the Yin-Yang type balancing of antagonisms.
