    • Single crystals of complex 1 instantaneously undergo desolvation; a colorless platelet of approximate dimensions 0.40X0.15 X 0.03 mm3 was covered with a thin layer of vacuum grease, rapidly mounted in a cryo loop and immediately exposed to a cold stream of N2. The structure was solved by dual space methods as implemented in SHELXD;[11] the best solution was associated with a correlation coefficient of 79.85 and allowed to locate most atoms of the eight symmetrically independent cyclodextrin moieties. The structure model was completed by difference Fourier syntheses and refined on F2 with SHELXL.[12] Resolution of the diffraction data and accuracy of geometric parameters are limited, and no H atoms could be associated with the solvent molecules. No attempt was made to refine part of the structure model with anisotropic displacement parameters, and no split positions for water oxygen were assigned. H atoms associated wi
