摘要:
采用溶液法合成一个捕获二维无限水层的多酸杂化化合物3H3［PMo12O40］·6C3N6H6·31H2O.X射线单晶衍射表明:标题化合物属于三方晶系,空间群为P-3;其晶胞参数a=1.754 0(9)nm,b=1.754 0(9)nm,c=1.330 5(3)nm,α=90°,β=90°,γ=120°,V=3.545 3(4)nm3.该化合物中的Keggin型多酸阴离子作为模板诱导了水簇形成,搭构成一个二维水层{(H2O)30}n,三氨基三嗪填充孔洞后增强了水簇的稳定性. 热失重分析和循环伏安测试结果表明:标题化合物具有较好的热稳定性和优良的氧化还原性能.
Abstract:
An polyoxometalates(POMs)compound 3H3［PMo12O40］·6MA·31H2O(1)(MA=Melamine)has been synthesized by solution evaporation method, which can trapped an infinite 2D water layers. X-ray single-crystal diffraction analysis revealed that the title compound crystallized in the trigonal system P-3 space group with a = 1.754 0(9)nm, b= 1.754 0(9)nm, c= 1.330 5(3)nm, α = 90°, β = 90°, γ = 120°, V= 3.545 3(4)nm3. The structure of the 2D-infinite water layers {(H2O)30}n was induced by the template effect of the Keggin-type POMs anion. The MA molecules filling in the pores enhanced the stability of the water layers. Thermogravimetric,and electrochemical studies have been carried out. The results showed that title compound have good thermal stability and electrochemical properties.
