摘　　要：利用水热合成法合成了目标化合物(C6H10N2)[2SiW12O40]。通过X射线单晶衍射仪确定了晶体结构,晶体属单斜晶系,空间群C2/m。通过红外、热重分析和循环伏安曲线对晶体进行了结构表征、晶体的热稳定性和氧化还原性研究。晶体中的α-Keggin阴离子、有机配体通过氢键相互作用,形成超分子化合物。A novel organic-inorganic hybrid supermolecular compound containing α-Keggin polyoxometalate （C6H10N2）2[SiW12O40]was prepared by hydrothermal synthesis and confirmed composition by single crystal X-ray diffraction. The title compound crystallizes in the monocline system, space group C2/m. The compound was characterized by IR. The redox properties and thermal properties were invesitaged by cyclic vohammogram curve and thermogravmetic analysis. The structure of the compound is consisted of HPPD and [SiW12O40]^2-, which are connected with hydrogen bonds to form supermolecular structure.
