摘要
采用分步降解法合成了２：１７钨砷酸钾杂多配合物．用元素分析，ＶＯ２＋光度滴定、紫外光谱、红外光谱、Ｘ－射线衍射、循环伏安、热重－差热分析对标题化合物进行了表征．实验结果表明，它具有一空缺α２型Ｄａｗｓｏｎ结构及不可逆的氧化还原性．较１：１１钨砷酸钾有更强的氧化性和比２：１８钨砷酸铵杂多配合物有稍高的热稳定性．
The K10As2W17O61· 18H2O was synthesized with the method of improved seguencedegradation. The title compound was characterized by elemental analysis. VOZ+titration, UV, IR, X-ray powder diffraction, CV and TG-DTA analysis. The results showed that the complex with ahole-Dawson structure and the hole made the oxidation-reduction irreversible. Its properties suchas spectra, redox behavior and thermal stability was discussed.
