Abstract

A family of organometallic compounds has been designed based on half-sandwich ruthenium complexes [(arene)Ru(L)X2] (X=Cl, I); this showed dynamic host-guest properties towards volatile molecules, caused by small local reversible structural rearrangements. These features derive from the supramolecular organization of the compounds in the solid state, based on a so-called wheel-and-axle pattern, that is known to favour guest inclusion. The molecular features of the Ru complexes (arene size and shape, ligand size and chemical properties, halogen nature) were screened in order to optimize the final performances of the materials. The design strategy has proven to be succesful, affording materials capable to dynamically exchange volatile molecules by gas-solid processes and solid-solid transformations without loss of crystallinity.
