【摘要】 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，并探讨了Ｌａ（ＩＰＡ）３·Ｈ２Ｏ对小麦幼苗根部生长的作用更多还原

【Abstract】 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.更多还原
