THE IMPROVENT OF H_6[Gew_(10)V_2O_(40)]xH_2O SYNTHESIS METHOD AND STUDY ON ITS PROPERTIES

本文首次报道了从三空缺的中间体Ｎａ１０ＣｅＷ９Ｏ３４·１８Ｈ２Ｏ（简记为ＧｅＷ９）出发，定向合成钒位于相邻齿顶的杂多配合物Ｈ６［ＧｅＷ１０Ｖ２Ｏ４０］─ＸＨ２Ｏ的方法。此法操作简单、省时、省料、产品纯度高．钒的位置确定，适于选择立体合成．此外，系统地研究了未见文献报道的该化合物的红外光谱、紫外光谱、顺磁共振谱和ｘ射线粉末衍射，并利用热重和差热以及变温红外变温ｘ射线衍射分析对其热稳定性做了详细讨论。

In this paper,We have been improved the synthetic method of H6[GeW10V2O40].xH2O,For the first the the compound has been synthesited from trivacant heteropoly tungstate B-α-[GeW9O34]10-The product has ben obtained by this method which has good purity and high yields. this method has many advantages of saving time, using reagents sparingly and operating easily. We have been first studied H6[GeW10V2O40] with ultimate analysis, IR, UV,ESR, TG, DTA and x-ray diffaction.
