The structure of the 1:1 adduct of [Rh(cod)(NH 3 ) 2 ][PF 6 ] (cod = 1,5‐cyclooctadiene) and α‐cyclodextrin (α‐CD) has been elucidated by an X‐ray structure analysis. The tub‐shaped cod ligand lies almost exactly above the center of the α‐CD cavity, into which it partilly protudes. The two NH 3 ligands interact with four secondary OH groups.
