A highly hydrated α-cyclodextrin/1-undecanol inclusion complex: crystal structure and hydrogen-bond network from high-resolution neutron diffraction at 20 K

The highly hydrated α-cyclodextrin/1-undecanol host–guest complex was studied by single-crystal neutron diffraction. The supramolecular multichannel assembly based on cyclodextrin dimers which act as building blocks, each fully enclosing the lipid guest, is stabilized by an exceptionally rich water-mediated hydrogen-bond network.
