| 摘要: 合成了2个新型的多齿配体：2，9-二-[1′-（2″-苯并咪唑基）-2′-氮杂-正丙基]-1，10-菲罗啉(L1)和2，9-二-[2′-（2″-苯并咪唑基）-3′-氮杂-正丁基]-1，10-菲罗啉(L2)并且用元素分析和 1H NMR谱作了表征。在25 ± 0.1 ℃，运用pH电位滴定法对这2个新的配体及其与过渡金属离子M(Ⅱ)(M=Co，Ni，Cu，Zn)和稀土金属离子Ln(Ⅲ)(Ln=La，Nd，Sm，Eu，Gd)的配合物进行了热力学稳定性研究。结果表明配体和金属离子的配位比为1∶1，但是，这2个系列的配合物在稳定性方面存在很大差异。 |

| Abstract: Two novel multidentate ligands: 2,9-bis-[1′-(2″-benzimidazolyl)-2′-aza-n-propyl]-1,10-phenanthroline (L1) and 2,9-bis-[2′-(2″-benzimidazolyl)-3′-aza-n-butyl]-1,10-phenanthroline (L2) were synthesized and characterized by elemental analysis and 1H NMR spectroscopy. The thermodynamic properties of the ligands and their complexes with transition metal ions M(Ⅱ) (M=Co, Ni, Cu and Zn) and rare earth metal ions Ln(Ⅲ) (Ln=La, Nd, Sm, Eu, Gd) have been investigated at 25 ± 0.1 ℃ using pH titration. The results show that the coordination ratio of the ligands to the metal ions is 1∶1. However, there is great difference in stabilities between two series of complexes. |
