二苯羟基乙酸稀土配合物的合成表征及导电性质的研究

Studies on Synthesis, Characterization and Electrical Conductivity of Rare Earth Complexes of Dibezenyl 2 hydroyl acetic Acid

合成了二苯羟基乙酸稀土固体配合物１４种．元素分析表明配合物的组成为ＲＥ（ＤＢＡ）３ｎＨ２Ｏ（ＤＢＡ＝Ｐｈ２Ｃ（ＯＨ）ＣＯＯ－，ＲＥ（Ⅲ）＝Ｌａ～Ｙｂ，Ｙ，ｎ＝４～６）．通过红外、紫外和核磁共振谱等对配合物的结构进行了表征．此外对Ｌａ、Ｐｒ、Ｇｄ、Ｄｙ和Ｙ５种配合物的导电性质进行了研究。

Fourteen solid complexes of dibezenyl 2 hydroyl acetic acid(DBA) with rare earth have been synthesized. The complex general formula, which was determined by elemental analysis, is RE(DBA). n H 2O (RE(Ⅲ)=La～Yb,Y). Their structure was characterized by IR, UV and NMR spectra, and so on. Besides, the electrical conductivity of the complexes of La, Pr, Gd, Dy and Y with DBA was measured,the results show the five complexes have an electrical conductivity similar to that of semiconductors.
