Determination of the crystal and molecular structures of the cyclohexa-amylose (a-cyclodextrin, a-CD)-methanol complex has shown that cyclohexa-amylose assumes an unstrained relaxed structure, which is stabilized by a ring of hydrogen bonds between 0-2 and 0-3 of adjacent D-glucopyranosyl residues, on inclusion of methanol.The results support the general mechanism (Figure 2) proposed for the formation of inclusion complexes.
