用三缺位杂多阴离子ｘＷ９Ｏｎ－３４（ｘ＝ｐ，Ｓｉ，Ｇｅ）为原料首次合成了３种以金属元素Ｓｒ为中心原子的混合型钨系杂多配合物。通过元素分析和热重分析得分子式为ＫａＨｂ［Ｓｒ（ｘＷ９Ｏ３４）２］·Ｈ２Ｏ；用ＩＲ、ＵＶ确证该阴离子具有Ｋｅｇ－ｇｉｎ结构；对其氧化还原性研究表明为两步双电子可逆还原过程。本文还研究了它们的光谱性质与稳定性能。

Synthesis and Characterization of HeteropolyComplexes of the Type KaHb[Sr(XW9O34)2]·mH2O Jin Surong\ Liu Shizhong\ Wang ZhengThree heteropolytungstate compounds containing metal element Sr were synthesized using the XW9On-34 (x=P,Si,Ge) by the first time.Their formula were determined by elemental analysis and TG analysis as KaHb[Sr(XW9O34)2]·mH2O.Their Keggin structure were testified by IR and UV spectrum.Besides, their stability were discussed.: heteropoly complex;\ alkaline earth metal element;\ synthesis
