Crystal and molecular structure of the γ-cyclodextrin–12-crown-4 1 : 1 inclusion complex

Abstract

The crystal structure of the γ-cyclodextrin–12-crown-4 1 : 1 inclusion complex has been determined by an X-ray analysis which shows that three γ-cyclodextrins are stacked along a four-fold rotation axis forming a channel-type structure and each γ-cyclodextrin includes a 12-crown-4 molecule in a similar orientation.
