    摘要: 論文提要內容：
    本論文合成一系列尿素酶模型之鎳(II)錯合物且性質由X-ray單晶繞射儀、UV-Vis光譜、元素分析儀及質譜儀來分析。

    尿素酶模型鎳(II)錯合物及配位基:
    (1) [Ni2(L1)(C7H4ClO2)(H2O)]
    (2) [Ni2(L1)(CH3COO)(2H2O)]
    (3) [Ni2(L2)(C7H4BrO2)(H2O)]
    (4) [Ni7(C27H27N4O3)3(CO3)2(H2O)6(OH)]


    L1: 4-chloro-2-((E)-4-(3-(2-((E)-5-chloro-2-hydroxybenzylideneamino)ethyl)-2-
    (5-chloro-2-hydroxyphenyl)imidazolidin-1-yl)but-1-enyl)phenol
    L2: 4-bromo-2-((E)-4-(3-(2-((E)-5-bromo-2-hydroxybenzylideneamino)ethyl)-2-
    (5-bromo-2-hydroxyphenyl)imidazolidin-1-yl)but-1-enyl)phenol
    L3: 2,4-dichloro-6-((E)-4-(3-(2-((E)-3,5-dichloro-2-hydroxybenzylideneamino)
    ethyl)-2-(3,5-dichloro-2-hydroxyphenyl)imidazolidin-1-yl)but-1-enyl)phenol


    加入尿素(Urea)與鎳錯合物反應，可藉由UV-Vis光譜測量來了解此錯合物是否具有反應活性，並藉由SQUID變溫磁化率的測定，了解鎳與鎳之間配位立體結構與磁性行為的關聯性。
    A seiries Urease model nickel(II) complexes as funtionl model compounds were synthesized and characterized by X-ray single crystal diffraction, UV-Vis spectroscopy, element analyzer, and mass spectroscopy analysises.

    Urease model nickel(II) complexes & ligands:
    (1) [Ni2(L1)(C7H4ClO2)(H2O)]
    (2) [Ni2(L1)(CH3COO)(2H2O)]
    (3) [Ni2(L2)(C7H4BrO2)(H2O)]
    (4) [Ni7(C27H27N4O3)3(CO3)2(H2O)6(OH)]
    L1: 4-chloro-2-((E)-4-(3-(2-((E)-5-chloro-2-hydroxybenzylideneamino)ethyl)-2-
    (5-chloro-2-hydroxyphenyl)imidazolidin-1-yl)but-1-enyl)phenol
    L2: 4-bromo-2-((E)-4-(3-(2-((E)-5-bromo-2-hydroxybenzylideneamino)ethyl)-2-
    (5-bromo-2-hydroxyphenyl)imidazolidin-1-yl)but-1-enyl)phenol
    L3: 2,4-dichloro-6-((E)-4-(3-(2-((E)-3,5-dichloro-2-hydroxybenzylideneamino)
    ethyl)-2-(3,5-dichloro-2-hydroxyphenyl)imidazolidin-1-yl)but-1-enyl)phenol

    These complexes have been characterized by IR spectroscopy, elemental analysis. Addition urea of reaction with nickel(II) complexes by UV-Vis spectroscopy, we can understand that nickel(II) complexes whether have urease activity. Magnetic susceptibilities were measured to understand magnetic behavior of these complexes.
