SEARCH Articles Figures Tables A composite drawing of the two a-cyclodextrin Kr 5H20 structures depicted in Figures 8a, b. The positions of the krypton atoms are projected into one a-cyclodextrin cavity to show the almost hexagonal distribution of the disordered krypton sites. The diagonal of the small hexagon formed by the krypton atoms is 1.1 A, the site near the glucose 5 which is rotated most towards the viewer is empty owing to steric interactions. [Publishers Imprint]
