【摘要】 本文合成了十四种稀土-α-甲基丙烯酸固体配合物,用化学方法确定其组成为REL₃, nH₂O（HL=C₄H₆O₂;RE=La,Ce,Pr,Nd,n=2;RE=Sm,Eu,Gd,Tb,n=1;RE=Dy,Ho,Er,Tm,Yb,Y,n=0）,用红外光谱、紫外可见光谱、核磁共振等测试技术对这些配合物的性质与结构进行了研究.更多还原

【Abstract】 AbstractIn this paper ,fourteen complexes of REL3. nH2O (HL = H2C C (CH3)COOH) were synthesized and characterized. According to the composition determined by chemical analysis ,the complexes were defined into three types :REL3 2H20 (RE La ,Ce ,Pr, Nd), REL3 H20 (RE = Sm ,Eu ,Gd, Tb ,and REL3 (RE Dy ,Ho , Er ,Tm ,Yb , Y). The experimental data obtained from spectrosecopic studies of LR , UV and H NMR provided powerful evidence for the synthesis of new complexes. Their properties and Structures have been discussed as well.更多还原
