稀土与α-萘乙酸配合物的合成和性质研究

PREPARATION AND CHARACTERIZATION OF RARE EARTH COMPLEXES WITH αNAPHTHALENEACETIC ACID

本文合成了１１种稀土与α－萘乙酸（一种植物生长素）的配合物。元素分析结果表明配合物的组成为ＲＥ（Ｃ１２Ｈ９Ｏ２）３·２Ｈ２Ｏ（ＲＥ＝Ｌａ，Ｃｅ，Ｐｒ，Ｎｄ，Ｓｍ，Ｅｕ，Ｇｄ，Ｄｙ，Ｅｒ，Ｙｂ，Ｙ），并通过配合物的ＩＲ，ＵＶ，Ｈ－ＮＭＲ，ＴＧ－ＤＴＡ，ＸＰＳ，磁化率，摩尔电导及溶解性的研究，表征了这些配合物的物理化学性质，结果表明配合物中的配体通过羧基氧原子与稀土离子配位。

おleven solid coordinnation complexes of rare earth with αnaphthaleneacetic acid as liganels have been prepared.The results of elemental analysis show that the new complexes have the composition of RE(C12H9O2)3·2H2O (RE=La,Ce,Pr,Nd,Sm,Eu,Gd,Dy,Er,Yb,Y).The IR,UV,HNMR,TGDTA,XPS,magntic sysceptibility,molar conductivity and solubilities of the compleses have also been studied.The results indicate that in these complexes of rare earth the ligand αnaphthaleneacetic connects the RE ions though the oxygen atoms of carboxyl groups.
