摘要
采用分步酸化法，合成了通式为Ｋ１３Ｈ２〔Ｌｎ（ＳｉＷ１０ＶＯ３９）２〕·ｘＨ２Ｏ（Ｌｎ＝Ｌａ、Ｃｅ、Ｐｒ、Ｎｄ、Ｓｍ、Ｅｕ）六种配合物。通过元素分析，红外、紫外光谱、Ｘ射线粉末衍射、磁化率测定和差热—热重分析等手段，对配合物进行了表征。
New heteropoly complexes with formula K_13H_2〔Ln(SiW_10V)_2〕·xH_2O(Ln=La,Ce,Pr,Nd,Sm,Eu)were prepared and characterized by elemental analysis,IR,UV,x-ray powder diffraction,magnetic susceptibility and TG-DTA. Magnetic measurement shows that the lanthanides in the complexes are still in the +3 oxidation state. Their decomposition temperature range is 450～500℃
