| 摘 要： | 为了研究在水热反应体系中铁原子的价态变化,通过水热方法合成了一个化合物(H3O)[Fe(2,2'-bipy)3]2[FeW12O40]·7H2O。X-ray单晶衍射仪测定该化合物具有三维超分子结构,其中阴离子[FeW12O40]5-和水簇通过氢键形成一维链状结构,热重分析表明:水簇(H2O)12的存在对化合物的稳定性起到了关键的作用,通过价键计算和磁性分析可以确定铁离子存在混合价态。

| Abstract: | In order to study the valence state change of iron atoms in a hydrothermal reaction system,a compound,namely,（H3O） [Fe（2,2＇-bipy）3]2[FeW12O40]·7H2O has been synthesized from hydrothermal reaction. The compound displays a 3D supramolecular framework containing 1D chain constructed by polyanions[FeW12O40]5-and water clusters through hydrogen bonding interactions determined by single-crystal X-ray diffraction. The existence of（H2O）12clusters plays an important role in stabilizing the solid-state structure evidenced by thermogravimetric（TG） analysis. The mixed-valence character of iron ions was confirmed by bond-valence calculations and magnetic analysis. |
