Solid–vapour reactions as a post-synthetic modification tool for molecular crystals: The enclathration of benzene and toluene by Werner complexes

The enclathration of benzene and toluene by Werner complexes has been described. In the case of toluene, time-lapse PXRD analysis reveals that solid–liquid and solid–vapour reactions proceed according to different pathways. These preliminary results suggest that solid–liquid reactions destroy the host structure, whereas the solid–vapour reactions allow post-synthetic modification.
