三取代杂多钨酸盐的导电性研究

Studies on Conductibility of Trisubstituted Heteropolytungstates

合成了过渡金属三取代的Ｋｅｇｇｉｎ结构杂多钨酸盐配合物，α－ＫｍＨｎ［ＸＷ９Ｏ３７Ｃｏ３（Ｈ２Ｏ）３］·ｍＨ２Ｏ（Ｘ＝Ｐ，Ｓｉ，Ｇａ），通过红外、紫外和可见光谱等进行了表征．ＴＧ－ＤＴＡ结果显示合成配合物中含有３种形式的水即结晶水、结构水和配位水．电导率测量则表明合成配合物具有较大的λ值和较低的Ｅａ，热稳定范围宽。

The trisubstituted heteropoly tungstates α -K mH n[XW 9O 37 Co 3(H 2O) 3]· m H 2O(X=P,Si,Ga) have been synthesized and characterized by IR and UV-Vis.The data of TG-DTA show that complexes possess three types water. The determination of conductibility exhibit that complexes with high σ and low E a values will be precious solid electrolyte.
