通过可溶性铌酸钾与粉状白钨酸的反应,合成了钨铌杂多阴离子化合[C~4H~9)N]~nK~7-n[NbW~11O~40H~2](n=5,6).根据化学分析、红外光谱和拉曼光谱等,认为[NbW~11O~40.H~2]^7-和[W~12O~40H~2]^6-具有相同结构骨架.

KNbO3 and powdery white tungstic acid in aqueous solution The structure of the anion may be proposed reasonably to be similar to that of [W12O40H2]6-, resulting from substituting of 1 WO6 group by 1 NbO6 group and giving [NbW11O40H2]7- according to the extreme similarity of IR and Raman spectra of these 2 different anions.
