Hoffman-type inclusion compounds

Both bpy and the extended bipyridyl ligand (9.10) have been used to produce square grid compounds, analogous to Hoffman-type inclusion compounds. The additional two carbon spacer in 9.10 apparently has the effect only of extending the grid dimensions in most cases with the exception of the NbO network... 

Liquid clathrates offer a great advantage over solid-state separations (e.g. by formation of Hoffman-type inclusion compounds, Section 9.4) because of the extremely fast mixing kinetics, the avoidance of the need to wait for crystallisation to occur and the easy separation of the two liquid phases. It should also prove possible to run liquid clathrate separations in a continuous extraction manner. The avalues of a number of liquid clathrate-based separations have been reported and are summarised in Table 13.1.
