| heal.abstract |
The crystal structures of the complexes of heptakis(2,3,6-tri-O-methyl)- β-cyclodextrin with indole-3-butyric acid and with 2,4- dichlorophenoxyacetic acid were studied by X-ray diffraction. The complexes crystallize in the monoclinic P21 space group. The host molecules are elliptically puckered and stacked along the a crystal axis, in a head-to-tail fashion, forming columns. One primary methoxy group of the host molecule of the complex with indole-3-butyric acid has the unusual trans-gauche conformation for permethylated CDs. All the secondary O-3-CH3 methoxy groups, some secondary O-2-CH3 and some primary methoxy groups pointing inwards the cavity enclose the indole or the 2, 4-dichlorophenoxy moieties of the guest molecules inside the cavity, while the chains of the guests protrude between two adjacent host molecules of the columns. The mean planes of the indole and 2,4-dichlorophenoxy moieties of the guests are nearly perpendicular to the mean planes of the elliptical heptagons defined by the O-4n atoms of the hosts. The carboxyl group of the guests form hydrogen bonds with oxygen atoms of the host molecules or with the water molecules found in the space between the complexes of the same column. © 2003 Elsevier Ltd.
