Anderson结构钼系过渡金属稀土盐的合成与性质研究

Synthesis and properties for the rare earth salt of molybdenum series transition metals with Anderson structure

首次合成了具有Ａｎｄｅｒｓｏｎ 结构的稀土元素钼系化合物，通式为Ｌｎ［ＸＭｏ６Ｏ２４Ｈ６］·ｎＨ２Ｏ（Ｌｎ ＝ Ｌａ，Ｃｅ，Ｐｒ，Ｎｄ，Ｇｄ；Ｘ＝ Ｃｒ（ Ⅲ） ，Ｃｏ（ Ⅲ） ，Ｎｉ（ Ⅱ） ，Ｚｎ（ Ⅱ） ；ｎ ＝７ ～１０） ，此类化合物属Ａｎｄｅｒｓｏｎ 结构的Ｂ型，其特点是杂原子与６个—ＯＨ 相连形成八面体．通过ＩＣＰ，ＩＲ，ＵＶ，ＣＶ 等方法对产物的性质进行了表征．电化学实验结果表明：杂原子为Ｃｏ（ Ⅲ） 的稀土盐对玻碳电极的表面有修饰作用．

Lanthanides molybdenum compound, Ln[XMo 6O 24 H 6]· n H 2O(Ln=La,Ce,Pr,Nd,Gd;X=Cr(Ⅲ),Co(Ⅲ),Ni(Ⅱ),Zn(Ⅱ); n =7～10), has firstly been synthesized. It belongs to the B-type of Anderson structure in which the heteroatom is coordinated by six — OH form octahedra. They were characterized by ICP,IR,UV,CV method, etc. The result of electrochemical experament shows that Co(Ⅲ) salt has an action of modification to the surface of G.C. electrode.
