【摘要】 用二缺位Ｄａｗｓｏｎ结构钨磷酸盐与四价钛离子反应首次合成出二钛取代Ｄａｗｓｏｎ结构钨钛磷三元杂多配合物．经元素分析和热重分析，确定该配合物的分子式为Ｋ１０［Ｔｉ２Ｐ２Ｗ１６Ｏ６２］·９Ｈ２Ｏ．用ＩＲ和ＵＶ确认该阴离子具有Ｄａｗｓｏｎ结构．用ＴＧＤＴＡ对化合物的热稳定性进行研究，发现钛取代后钨磷酸盐热稳定性增强．讨论了标题化合物的光谱性质和热性质更多还原

【Abstract】 A newly disubstituted Dawson anion with tetravalent heteroelement titanium has been synthesized from the dilacunary precursor K 10 Na 2H 2P 2W 16 O 62 ·18H 2O by the first time .Its Dawson structure was testified by IR and U V spectrum .Its formula was determined by element analysis and TG analysis as K 10 Ti 2P 2W 16 O 16 O 62 ·9H 2O.Besides,its optical and thermal properties were discussed.更多还原
