A pure inorganic porous framework based on the tungstoferrate[FeW_(12)O_(40)]~(5-),Fe(H_2O)_6H[Na_6FeW_(12)O_(40)]_2·44H_2O(1) was obtained by the conventional aqueous solution method and characterized by elemental analysis,TG,FT-IR,UV-vis spectroscopy. Single-crystal X-ray diffraction analyses reveal that compound 1 crystallizes in the space group Fm-3m,which is composed of a porous inorganic framework[Na_6FeW_(12)O_(40)]_n with two kinds of pores A and B,accommodating Fe(H_2O)_6 units in pore A,which was observed rarely in the pure inorganic framework.
A pure inorganic porous framework based on the tungstoferrate [FeW 12 O 40] ~ (5 -), Fe (H 2 O) 6H [Na 6 FeW 12 O 40] 2 · 44H 2 O was obtained by conventional aqueous solution method and characterized by elemental analysis, TG, FT-IR, UV-vis spectroscopy. Single-crystal X-ray diffraction analyzes reveal that the compound 1 crystallizes in the space group Fm-3m, which is composed of a porous inorganic framework [Na_6FeW_ (12) O_ (40)] _ n with two kinds of pores A and B, accommodating Fe (H_2O) _6 units in pore A, which was observed rarely in the pure inorganic framework.
