稀土元素1∶6系列钼钴酸盐的合成与性质研究

Studies of synthesis and properties of lanthanides 6-molybdocobaltate

首次合成了具有Ａｎｄｅｒｓｏｎ 结构的稀土元素钼钴杂多酸盐Ｌｎ［ＣｏＭｏ６Ｏ２４Ｈ６］·ｘＨ２Ｏ，（Ｌｎ ＝ Ｌａ，Ｃｅ，Ｐｒ，Ｎｄ，Ｇｄ，ｘ＝ ７ ～１０）．此类化合物属Ａｎｄｅｒｓｏｎ 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，ＴＧ－ ＤＳＣ，ＣＶ，ＸＲＤ

It was first reported that Ln[CoMo 6O 24 H 6]· x H 2O with Anderson structure (Ln=La,Ce,Pr,Nd,Gd, x =7～10) were synthesized.The compounds were Anderson structure of B type, which was noted that the heteroatom coordinated by 6 OHs form octahedron structure.They were characterized by ICP,IR,UV,TG-DSC,CV and XRD spectra.
