The exchange of carbonyls is a common feature for metal carbonyl compounds in solution whereas in the solid state high interatomic potential energy barriers cause this occurrence to be highly unlikely; it is shown that the compartmentalization of (arene)Cr(CO)(3) in the beta-cyclodextrin cavity removes any constraint and thereby facilitates the rotation of the Cr(CO)(3) group in the solid state.

Abstract
The exchange of carbonyls is a common feature for metal carbonyl compounds in solution whereas in the solid state high interatomic potential energy barriers cause this occurrence to be highly unlikely; it is shown that the compartmentalization of (arene)Cr(CO)(3) in the beta-cyclodextrin cavity removes any constraint and thereby facilitates the rotation of the Cr(CO)(3) group in the solid state.
