| 中文摘要: |
| 在水热条件下合成了两个Keggin型多金属氧簇构筑的有机无机杂化化合物：[CuⅠ(2,2"?bipy)2]{[CuⅠ(2,2"?bipy)2]2][PW12O40]}.4H2O(1)和{[(H3bpdc)3][PW12O40].H2bpdc}. 2H2O(2),并通过元素分析,IR,热失重曲线和单晶X?射线衍射等手段确定了其组成和结构。化合物(1)属于单斜晶系,P2(1)/n空间群。化合物(2)属于三斜晶系,P-1空间群。化合物(1)中2,2′?联吡啶?3,3′?二羧酸(H2bpdc)经原位脱羧反应形成{[CuⅠ(2,2"?bipy)2]2[PW12O40]}-阴离子和[CuⅠ(2,2"?bipy)2]+配位阳离子,并通过氢键和π-π堆积作用形成一维链状结构。化合物(2)中多酸阴离子和2,2′?联吡啶?3,3′?二羧酸有机组分通过氢键和静电引力形成三维超分子网络。电化学研究表明,两种化合物都存在三步氧化还原过程。 |

| Two novel organic-inorganic hybrid constructed from kegging polyoxometalate [CuⅠ(2,2"?bipy)2]{[CuⅠ(2,2"?bipy)2]2][PW12O40]}.4H2O(1) and {[(H3bpdc)3][PW12O40].H2bpdc}. 2H2O (2)was synthesized under hydrothermal condition and characterized by elemental analysis, IR, TG, CV and single-crystal X?ray diffraction.The compound 1 crystallized in a monoclinic crystal system, with space group P2(1)/n,compound 2 crystallized in a triclinic crystal system, with space group P-1.The compound 1 formed a 2D layered structure by hydrogen bond and π-π stacking of 2,2"-bipyridine. The compound 2 formed a 3D supramolecular architecture by hydrogen bond and electrostatic attraction. The cyclic voltammogram indicated that three couples redox waves were observed on the compound 1 and 2 modified carbon paste electrode. |
