摘要
本文报道了两种新型-N-乙酸取代氮氧杂大环的合成,并制得了它们的三价镧系离子的固体配合物(P_m除外),所有这些配合物都进行了元素分析,红外光谱,电导测定以及热分析等手段的表征。
The syntheses and characteriz ation of two new N-functionalized macrocyclic ligands con- taining oxygen and nitrogen heteroatoms are reported in this paper. The ligands are 1,12-diaza- 3, 4: 9, 10-dibenzo-5, 8-dioxacyclopentadecane-N, N' -diacetic acid (H_2L^1) 1, 12, 15-triaza- 3, 4:9, 10-dibenzo-5, 8-dioxacycloheptadecane-N^1, N^11, N^111-triacetic acid (H_3L^2). In the medium of methol orwater, we have obtained their lanthanide complexes, L_nL^1 (NO_3). mH_2O, L_nL2KNO_3. nH_2O (Ln=La-Lu, P_m excluded, m=1-4, n=0-5). All these complexes were charact-erized by 1R, elemental analysis, conduc-tivity masurement and thermal analysis.
