摘要

本論文中，先以醛類和胺類反應合成Schiff-base配位基L1
∼L4在和鐵離子反應，形成多核鐵(III)錯合物，分別為：

(1)[Fe(L1)(TBC)]

(2)[Fe2(L2)2(3,5-DTBC)2]

(3)[Fe4(L3)4]

(4)[Fe6(L4)4(3,5-DTBC)4Cl2]

其中L1 ︰2-((E)-(2-(2-aminoethylamino)ethylimino)methyl)-4-chlorophenol
L2 ︰(E)-2-((pyridin-2-yl)methyleneamino)-4,6-di-tert-butylphenol
L3 ︰N,N,-bis(salicylidene)ethane-1,2-diamine
L4 ︰((E)-2-((1H-imidazol-5-yl)methyleneamino)ethyl)-
ethane-1,2-diamine
TBC = Tetrabromocatechol
3,5-DTBC = 3,5-Di-tert-butyl-catechol

經由單晶結構的解析，錯合物之元素分析組成、紅外線光譜及
變溫磁化率(2-300K)等測定，探討其磁性行為，且與H2O2反應有
觸酶活性反應。

In this thesis, the preparations, crystal structures, magnetic properties and catalase activity of Iron(III)
complexes with substituted Schiff-base ligands(1)∼(4)
are reported：

(1)[Fe(L1)(TBC)]

(2)[Fe2(L2)2(3,5-DTBC)2]

(3)[Fe4(L3)4]

(4)[Fe6(L4)4(3,5-DTBC)4Cl2]

where, L1 ︰2-((E)-(2-(2-aminoethylamino)ethylimino)methyl)-4-chlorophenol
L2 ︰(E)-2-((pyridin-2-yl)methyleneamino)-4,6-di-tert-butylphenol
L3 ︰N,N,-bis(salicylidene)ethane-1,2-diamine
L4 ︰((E)-2-((1H-imidazol-5-yl)methyleneamino)ethyl)-ethane-1,2-
diamine
TBC︰Tetrabromocatechol
3,5-DTBC︰3,5-Di-tert-butyl-catechol

These compounds have been characterized by elemental analysis, IR spectra, and variable temperature(2∼300K) magnetic susceptibilities were measured to understand the magnetic behavior. These compounds exhibit catalase-like activity toward H2O2 disproportation.
