Figure 5
α-CD dimer. Hydrogen bonds are represented by green dashed lines. Six intermolecular (intradimer) hydrogen bonds alternately involving all O3—H hydroxyls are observed. In each CD moiety, six intramolecular hydrogen bonds alternately involving the O3—H and the O2—H secondary hydroxyl are observed. All H atoms of the secondary hydroxyls have two positions (s.o.f. = 0.5). |
