✦ Synopsis

Addendum to the previous study [Carbohydr. Res., 259 (1994) 1-12], to show that C-O • • • O coordination angles are not a useful criterion for the identification of hydrogen bonds if the H-atom positions are not known.

The statistical relation between intermolecular 0 . . . 0 separations and the occurrence of hydrogen bonding is described for six high-resolution neutron crystal structures of vclomalto-oligosaccharide (cyclodextrin) complexes. All 0 \* \* -0 contacts shorter than 3.0 A are actually associated with
