【摘要】 {AlW₁₂}型多金属氧酸盐的合成较为困难,但其表面电荷密度大,配位类型多样,因此具有潜在的应用前景。本文利用水热法,合成了两种新型的铝钨酸盐:[Ag（bpy）][{Ag（bpy）)₂(H₂AlW₁₂O₄₀)]·H₂O（1）,[{Cu（bPy）)₃(H₂AlW₁₂O₄₀)]·H₂O（2）（bpy=4,4-bipyridine）。结构分析表明,两种化合物含有相似的三链带结构,但不同的是,化合物1中[AlW₁₂O₄₀]^5-是通过对称位的两个氧原子与Ag⁺配位;化合物2[AlW₁₂O₄₀]^5-作为三齿配体,通过两个相邻的端氧及其中间的桥氧连接相应的Cu⁺。这两种化合物还具有较好的电化学和光催化性质。更多还原

【Abstract】 {AIW₁₂} polyoxometalate that are more difficult to be prepared have potential application p rospectbecause of their higher surface charge density and a wider variety of coordination t ypes.Two novel aluminotungstates,[Ag（bpy）][{Ag（bpy）}₂(H₂AIW₁₂O₄₀)]·H₂O（1）,[{Cu（bpy）}₃(H₂AI W₁₂O₄₀)]·H₂O（2）（bpy=4,4-bipyridine）,have been synthesized under hydrothermal conditions in this paper.The structural analysis reveals that compounds contain similar three-chai n belts.Whereas the difference is that[AIW₁₂O₄₀]^5- of lcoordinateswith Ag⁺ by two oxyge n atoms in a symmetrical position,[AIW₁₂O₄₀]^5- unit link Cu⁺ with two adjacent terminal o xygens and one bridging oxygen atom as tridentate ligand in 2.The two compounds exhibi t better electrochemical and photocatalytic properties.更多还原
