Abract:

The first thorium framework compound with mixed-valent phosphorus based ligands phosphite and pyrophosphate, [BMMim]2[Th3(PO3)4(H2P2O7)3] (ThP-1), was synthesized from ionothermal reaction concurrent with the partial oxidation of phosphorus acid. The overall structural topology of ThP-1 highly resembles that of MOF-5, containing only one type of three-dimensional channels with the window size of 11.32 × 11.32 Å2. The free void volume of ThP-1 is 50.8%, making this compound one of the most porous purely inorganic actinide based framework materials. More importantly, ThP-1 is highly stable in aqueous solutions over an extremely wide pH range from 1 to 14, which may find potential applications in the selective ion-exchange and catalysis.
