摘　　要：本文合成了十二个稀土与Ｌ－组氨酸（Ｌ－Ｈｉｓ）的固体配合物，元素分析结果表明配合物的组成为Ｌｎ（Ｈｉｓ）３（ＮＯ３）３２Ｈ２Ｏ（Ｌｎ＝Ｙ，Ｌａ，Ｃｅ，Ｐｒ，Ｎｄ，Ｓｍ，Ｅｕ，Ｇｄ，Ｔｂ，Ｄｙ，Ｅｒ，Ｔｍ）。并通过配合物的ＩＲ、ＵＶ、Ｈ－ＮＭＲ、ＴＧ－ＤＴＡ、磁化率及在水中的摩尔电导等的研究，表征了这些配合物的物理化学性质，结果表明稀土组氨配合物中配体通过羧基氧原子与镧系离子配位。In this thesis,twelve solid coordination comlexes of rare earths with L Histidine as ligands have been prepared.The results of elemental analysis show that the new complexes have the composition of Ln(His) 3(NO 3) 32H 2O (Ln=La,Ce,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Er,Tm,Y).The IR,UV, 1H-NMR, TG-DTA,magnetic susceptibility,molar conductivity and their solubilities of the complexes in H 2O and organic solvents have also been studied. The results indicated that in these complexes of rare earths,the Ligand L Histidine connects the Ln ions through the oxygen atoms of carboxyl groups.
