| 摘要: 以2,9-二甲基-1,10-菲咯啉为初始原料，合成了2,9-二甲基-1,10-菲咯啉的α-氨甲基吡啶衍生物-N,N'-二(2'-吡啶基)甲基-1,10-菲咯啉-2,9-二甲胺(L)。该配体经过元素分析、红外光谱、核磁共振氢谱表征。在25±0.1℃、I=0.1mol·dm-3NaNO3的条件下，用pH电位滴定法测定了该配体在水溶液中的质子化常数及其分别与Mn(Ⅱ),Co(Ⅱ),Ni(II),Cu(Ⅱ)和Zn(Ⅱ)的配合物的稳定常数,提出了配合物的可能结构。进一步讨 |

| Abstract: Starting from 2,9-dimethyl-1,10-phenanthroline, its α-(aminomethyl)pyridine derivative N,N'-bis(2'-pyridine)methyl-1,10-phenanthroline-2,9-dimethanamine (L) was synthesized and was characterized by elemental analysis, IR, 1H NMR. The protonation constants of the ligand L, the stability constants of M Ⅱ L (M=Mn, Co, Ni, Cu, Zn) binary complexes have been determined by pHpotentiometric titration method at 25±0.1℃, I =0.1mol·dm-3 NaNO3. The probable structures of the corresponding complexes were proposed. The internal cause for larger stability constants was further discussed. |
