摘要：

Combination of anionic [V10O28](6-) and cationic [AlO4Al12(OH)(24)(H2O)(12)](7+) polyoxometalate clusters in an aqueous solution resulted in immediate hydrogel precipitation formation. This gel has the clusters in a 1:1 ratio arranged alternatively to form a short-range ordering. The precipitate, upon drying at room temperature, converts into a monolithic gel probably through the condensation of the [AlO4Al12(OH)(24)(H2O)(12)](7+) clusters as evidenced by the change of Al-27 solid-state MAS NMR data.
