In the formation of the βCD·1 adduct (shown on the right), the complex trans ‐[Pt(PMe 3 )Cl 2 (NH 3 )] 1 inserts its hydrophobic PMe 3 ligand into the narrow opening of the β‐cyclodextrin (βCD) cavity, as has been shown by an X‐ray structure analysis. The neutral complex is bound only by βCD, but not by αCD. This finding is of interest with regard to the development of water‐soluble catalysts and drug delivery systems.
