摘要 在水热条件下,合成出一例新的具有Keggin型结构的杂多酸化合物[PW12O40](C2N3H4)3·6H2O(1)。利用单晶X-射线衍射分析了该化合物的结构,结果表明该化合物属于三方晶系,R-3空间群,晶胞参数为a=1.79590(3)nm,b=1.79590(3)nm,c=2.43480(5)nm,α=90°,β=90°,γ=120°,V=6.8008(2)nm3,Z=6,R1=0.0458,ωR2=0.1116。在该化合物中,质子化的1,2,4-三氮唑与[PW12O40]3-通过氢键作用形成三维超分子结构。 A new Keggin- type supramolecular compound,[PW12O40]( C2N3H4)3·6H2O was synthesized under hydrothermal conditions. The structure was characterized by single crystal X- ray diffraction,which crystallized in the trigonal system,space group R- 3,a = 1. 79590( 3) nm,b = 1. 79590( 3) nm,c = 2. 43480( 5) nm,α = 90°,β = 90°,γ = 120°,V = 6. 8008( 2) nm3,Z =6,R1= 0. 0458,and ωR2= 0. 1116. In compound of [PW12O40]( C2N3H4)3·6H2O,through hydrogen bond interactions,protonated triazole and [PW12O40]3-were linked into a three- dimensional structure.
