【摘要】 多金属氧酸盐(简称多酸)因其结构的复杂多样性以及在催化、光化学、电磁学和医学等领域的广泛应用而备受人们关注[1,2]。无机-有机杂化材料兼有无机材料与有机材料的特性成为材料科学的研究热点。本文报道了一种新型的双支撑Keggin型多金属氧酸盐二聚物[Zn(C10H8N2)2(H2O)2]2[SiW12O40][C10H8N2]2·4H2O(1),并通过IR,ICP,XPS,TG,X-射线衍射进行了表征。如图1所示,分子结构是由饱和Keggin阴离子[SiW12O40]4-单元两端通过W-O-Zn桥连两个Zn(C10H8N2)2(H2O)2基团而成的二聚物,有机金属阳离子与二聚体通过静电相互作用。
【Abstract】 Polyoxometalates have attracted great interest due to their structural diversity and extensive application in catalysis,photochemistry,electromagnetism and medicine.Inorganic-organic hybrid materials possess the characteristics of inorganic material and organic material makes them become the focus in the material science.This paper report a new type double-supported Keggin polyoxoanion dimer and characterized by IR,ICP,XPS,TG,X-ray structure analysis.As shown in fig.1,the molecular structure consists of anionic Keggin SiW12O40 unit and two Zn(C10H8N2)2(H2O)2 groups forming dimer,in which Zn(C10H8N2)2(H2O)2 and SiW12O40 are coordinated through bridging O atoms,organic metal cation interacts with dimer by electrostatic interaction.
