稀土与1,1′——二茂铁二甲酸配合物的合成和表征

SYNTHESIS AND CHARACTERIZATION OF RARE EARTH COMPLEXES WITH FERROCENE 1,1′--DICARBOXYLATE

本文合成了1,1′———二茂铁二甲酸的15种稀土配合物,并进行了组成、IR、MS、DTA-TG、X-射线粉末衍射表征。由元素分析,DTA-TG、MS确定了配合物的组成为Ln2[Fc(COO)2]3·6H2O(Ln=La-Lu、Y除Pm外);IR研究表明—COO-是以对称螯合双齿进行配位的;X—射线粉末衍射说明除La外,其它配合物具有相同晶型。

The synthesis and characterization of fifteen rare earth complexes with ferrocene 1,1′--dicarboxylate were described.The composition of these complexes formulated as Ln23·6H2O(where Ln=La-Lu?Y,except Pm)has been studied by means of elemental analyses?some of DTA-TG and MS;FT-IR(4000-400cm-1)exhibits that the -COO- coordinated by symmetry chealating bidentate;Some of X-ray powder diffraction reaveal these complexes except La′s may be isomorphous.
