摘　　要：采用水热法合成了一种新型多酸基无机-有机杂化材料{[Co(btp)(Hbtp)(H_(2)O)_(3)](PW_(12)O_(40))·3H_(2)O}_(n)(1),并对化合物1进行了结构测定。X射线单晶衍射结果显示,Co(Ⅱ)离子通过btp配体连接形成一维链,[PW_(12)O_(40)]^(3-)游离于相邻一维链相互交叉形成的孔隙中,从而扩展成三维结构。热重分析表明化合物1具有良好的热稳定性。此外,还对化合物1的质子导电性能进行了研究。结果表明,化合物1在358 K和98%RH条件下的质子电导率为6×10^(-5)S·cm^(-1)。A new polyoxometalate-based inorganic-organic hybrid material{[Co(btp)(Hbtp)(H_(2)O)_(3)](PW_(12)O_(40))·3H_(2)O}_(n)(1)was synthesized by hydrothermal method and the structure of compound 1 have been determined.X-ray single-crystal diffraction reveals that Co(Ⅱ)ions are linked with btp ligands to form one-dimensional chains,and[PW_(12)O_(40)]^(3-)are dissociative in the pores formed by the cross of adjacent one-dimensional chains,thus expanding into a three-dimensional structure.Thermogravimetric analysis shows that compound 1 has excellent thermal stability.Moreover,an investigation of the proton conductivity of compound 1 was carried out.As a result,the proton conductivity of compound 1 at 358 K and 98%RH is 6×10^(-5)S·cm^(-1).
