| 摘 要： | 合成了三缩四乙二醇-二-(8-喹啉基)醚(Ⅰ)配体,并首次合成了与十四个稀土硝酸盐的固体配合物.用IR、TG、DTA等测试确定固体配合物组成为[Ln(NO_3)_3]_3(Ⅰ)_2(Ln=La、Ce、Pr、Nd)和CLn(NO_3)_3)_3(Ⅰ)·H_2O(Ln=Sm-Yb和Y).配体(Ⅰ)和配合物[La(NO_3)_3)]_3(Ⅰ)_2核磁共振谱分析表明,醚链上的质子向低场位移,喹啉环上质子向高场位移,这说明镧与配体(Ⅰ)中喹啉上的氮是直接配位的.

| Abstract: | The di-8-hydroxyquinoline-tetra-ethylene glycol ether(I) has been synthesized as a ligand. The solid coordination compounds of fourteen rare earth elements with this ligand have been synthesized first time. The composition of these coordination compounds are (Ln(NO3)3)3I2 (Ln=La, Ce, Pr, Nd) and (Ln(NO3)3)3I?H2O (Ln=Sm-Yb and Y). These structures were firmed by IR, TG and DTA methods. The 'HNMR spectrum of the ligand (I) and coordination compound (La(NO3)3)3(I)2 shows the proton in ether bond shifts to low field and the proton in quinoline ring shifts to high field. This expresses La to coordinate with nitrogen atom in quinoline of ligand (I) directly. |
