Abstract

A pure inorganic porous framework based on the tungstoferrate [FeW12O40]5−, Fe(H2O)6H[Na6FeW12O40]2·44H2O (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 [Na6FeW12O40]n with two kinds of pores A and B, accommodating Fe(H2O)6 units in pore A, which was observed rarely in the pure inorganic framework.
