Molecular interpenetration within the columnar structure of crystalline anilino-β-cyclodextrin

A single crystal of mono(6-anilino-6-deoxy)-beta-cyclodextrin was prepared, and its crystal structure was determined by X-ray crystallographic analysis, which clearly revealed that the anilino groups are consecutively included intermolecularly into the adjacent cyclodextrin cavities in the crystal, thus giving rise to a consolidated column, located on a 2(1)-screw axis.
