| 摘 要： | 合成2—(4—异丁基苯)丙酸希土十五种固体配合物,R_B(Ⅱ b)_3 nH_2O(R_B=La-Pr,n=2;Nd,1.5;Sm,1;Eu,Gd,r,0.5;Tb-Lu,0).X-射线粉末衍射分析表明15种配合物都是无定形的.研究这些配合物的红外光谱、~1H-NMR、摩尔电导及溶解性等性质,进行差热一热重分析.配合物中羰基的对称、反对称伸缩振动频率之差值表明配位体羰基的配位方式是双齿或多聚螯合配位.拉曼光谱中R_B-O的振动频率为491,370,260cm~(-1).

| Abstract: | Fifteen solid rare earth 2 - ( 4 - isobutyphenyl ) propionates( Ibuprofenum, Ib ) complexes have been synthesizd with general formula as RE ( Ib ):nH2O ( RE = La-Pr, 11= 2 ;Nd, l.5; Sm, 1 ; Eu, Gd, Y, 0.5; Tb-Lu, 0 ) . The complexes have been characterized by element analysis, IR, 1H-NMR, molar canductance and TG-DTA. The complexes are isomorphism to X-ray. The difference V ( = vas, coo- vs,coo-) between asystemic and systemic stretching frequencies of carboxylates in the complexes indicated that the coordination mode of carboxylate ions is bidentate coordination or polymeried dielation. The vibration frequencies of RE-O in Raman spectra are 491, 370 , 260 cm-1. |
