| 摘 要： | 以三氨乙基胺和N－甲基咪唑醛为原料合成了三角架多咪唑配体((min)3tren)，并合成了五个过渡金属配合物：[Zn(min)3tren](ClO4)21， [Cu(min)3tren](ClO4)22, [Ni(min)3tren](ClO4)23, [Co(min)3tren](ClO4)24, and [Mn(min)3tren](ClO4)2CH3CN5，通过元素分析，摩尔电导率，红外和电子光谱确定了化合物的组成。对配合物4和5进行了晶体结构测定。结果表明，在这两个化合物中金属原子均处于扭曲的八面体配位环境，分别与三个亚胺氮原子和三个咪唑氮原子配位。配合物4和5的电化学研究表明在乙腈溶液中，有[Co-O2]n-和[Mn-O2]n-存在，认为4和5是很好的超氧化物清除剂。

| Abstract: | Five new metal transition metal complexes formed with tripodal polyimidazole ligand tri{2‐[2‐(1‐methyl)imi‐dazoly](methylimino)ethyl}amine ((min)3tren), [Zn(min)3tren](ClO4)2 ( 1 ) [Cu(min)3tren](ClO4)2 ( 2 ), [Ni(min)3tren]‐(ClO4)2 ( 3 ), [Co(min)3tren](ClO4)2 ( 4 ), and [Mn(min)3tren](ClO4)2·CH3CN ( 5 ) were synthesized and characterized by elemental analysis, molar conductances, IR and electronic spectra. Analytical results show 1:1 metal‐ligand stoichiometry and 2:1 type of electrolyte in all metal complexes. The crystal structures of 4 and 5 have been determined. The metal atoms in 4 and 5 , being in distorted [MN6] octahedra, are coordinated with three imine nitrogen atoms and three imidazole nitrogen atoms. |
