摘要
合成了双(9-钨锗)过渡金属杂多配合物:K12H6[M(GeW9O34)2]·mH2O[M=Ni2+,Zn2+,Cu2+,Fe2+,Mn2+]。通过元素分析,红外,紫外,极谱,循环伏安及热分析等手段进行了表征。结果表明,所合成配合物具有Keggin结构。与GeW12相比,所合成配合物热稳定性降低,氧化能力增强。
Five heteropoly 9-tungstogermanates K12H6[M (GeW9O34 )2]. mH2O(M = Fe2+, Ni2+,Cu2 +, Mn2+, Zn2+ )have been synthesized and characterized by elemental analysis,UV,IR,polarogram,CV and TG-DTA. The results indicate that these new compounds have Keggin anion structures. In comparison with GeW12,the thermal stabilites of heteropoly compounds M(GeW9)2 decrease and their oxidation abilities increase greatly.
