稀土(Ⅲ)与噻吩甲酰基吡唑啉酮及2,2′-联吡啶混配配合物的研究

Study on Mixed Ligand Complexes of Rare Earth(Ⅲ) with Thenoyl Pyrazolone and 2,2′-Dipyridine

在溶剂中，合成了８种稀土（Ⅲ）与１－苯基－３－甲基－４－（２－噻吩甲酰基）吡唑啉酮－５（ＨＰＭＴＨＰ）及２，２′－联吡啶（ｂｉｐｙ）形成的混配配合物，经测定其组成为ＲＥ（ＰＭＴＨＰ）３ｂｉｐｙ，其中ＲＥ为Ｎｄ、Ｓｍ、Ｅｕ、Ｇｄ、Ｔｂ、Ｄｙ、Ｈｏ、Ｅｒ。通过红外光谱、紫外光谱、核磁共振谱、差热－热重分析、Ｘ射线粉末衍射分析和摩尔电导分析，初步研究了这些配合物的结构及性质。

The eight mixed ligand complexes of rare earth(Ⅲ) (RE=Nd,Sm,Eu,Gd,Tb,Dy,Ho and Er) with 1-phenyl-3-methyl-4-(2-thenoyl)-pyrazolone-5(HPMTHP)and 2,2′-dipyridine(bipy) have been synthesized in the solvents.According to elemental analysis, the complexes have composition of RE(PMTHP) 3bipy.The structures and properties of these complexes were studied by IR,UV,′HNMR, thermal analysis, X-ray diffraction and molar conductivity.
