Phosphates of Gallium and Indium

The use of fluoride in the synthsis of open-framework GaPOs has been ex- 

Since the first report in 1997 [60], a large number oftin(II) phosphate frameworks with different dimensionalities have been reported. Tin(II) is mainly found in 

The discovery of the tin(II) phosphate family led to the search for other systems containing lone pair cations, such as antimony(III). This indeed has turned out to be feasible, and an extensive range of antimony(III) phosphates and fluorophos-phates has been discovered [65]. As with the tin compounds, the structures appear to be open but the presence of lone pairs protruding into the cavities reduces their porosity.
