摘　　要：在双氧水存在条件下,合成了一例Wells-Dawson型铌钨混配多酸K3.5Na4[H4.5(NbO2)6P2W12O5 6]·12.5H2O(1),X射线单晶结构分析表明,化合物1的多阴离子是一个六过氧铌基团取代的P2W12衍生物.六个铌原子分别与五个来自多酸框架上的氧原子和一个端位的过氧单元配位.另外,对化合物1的光催化产氢性能进行了初步研究.A W/Nb mixed-addendum polyoxometalate K3.5Na4[H4.5（NbO2）6P2W12O56]·12.5H2O（1）has been prepared under acid aqueous solution and in the presence of peroxide.X-ray structure analysis reveals that the polyanion of 1 is a hexa（peroxoniobium）-substituted P2W12 derivative.Each of the six niobium atoms is coordinated by five oxygen atoms and one terminalη2-coordinated peroxo unit.Furthermore,the photocatalytic H2 evolution activity of 1 has also been investigated.
