吲哚-3-丙酸稀土二元配合物的合成表征和生物活性

Synthesis, Characterization and Bioactivity of Rare Earth Binary Complexes Containing Indole 3 Propionic Acid

合成了１５种稀土二元配合物．其组成为ＲＥ（ＩＰＡ）３（ＲＥ＝Ｌａ、Ｃｅ、Ｐｒ、Ｎｄ、Ｓｍ、Ｅｕ、Ｇｄ、Ｔｂ、Ｄｙ、Ｈｏ、Ｅｒ、Ｔｍ、Ｙｂ、Ｌｕ、Ｙ；ＩＰＡ＝吲哚３丙酸根）．通过化学分析、红外光谱、１ＨＮＭＲ谱、Ｘ射线粉末衍射和热谱等方法对新合成二元配合物的结构及性质进行了研究。

Fifteen binary rare earth complexes with indole 3 propionic acid were prepared in ge neral formula of RE(IPA) 3· n H 2O(RE=La,Ce,Pr,Nd,Sm,Eu,Gd,Tb, n =1; RE=Dy, Ho, Er,Tm,Yb,Lu,Y, n =0; IPA=indole 3 propionic acid). The compositions and structures of the complexes have been investigated by IR, TG, XRD and 1H NMR techniques. Their effects on the growth of wheat seedling has been examined briefly.
