摘　　要：利用水热法合成两种多酸基复合物,通过元素分析、红外光谱、X-射线粉末衍射和X-单晶衍射仪对其结构进行表征,确定分子式为[Cu_5(pz)_6](PW_(10)~ⅥW_2~ⅤO_(40))和[Cu_5(pz)_6](HSiW_(10)~ⅥW_2~ⅤO_(40)).结构分析表明两种复合物为同构异质体,存在一种具有12个Cu核的大环孔道结构.此外对两种复合物的光催化性质进行了研究.Two Polyoxometalate-based compounds were synthesized by hydrothermal method and their structures were characterized by elemental analysis,IR,X-ray powder diffraction and X-ray single crystal diffraction. The results showed that the molecular formula was [Cu5（ pz）6]（ PW（10）^ⅥW2^ⅤO（40）） and [Cu5（ pz）6]（ HSiW（10）^ⅥW2^ⅤO（40））. Structural analysis showed that the two complexes were isomorphic and there was a macrocyclic pore structure with 12 Cu nuclear. In addition,the photocatalytic properties of the two complexes were also investigated.
