一維鏈狀銅(Ⅱ)錯合物之合成、晶體構造與磁性之研究
Synthesis, Crystal Structures and Magnetic Properties of 1-D Cu(II) Polymer Complexes
摘要
本篇論文以Schiff-bases的方式合成配位基，使用疊氮、二氰胺等架橋基，加入過渡金屬銅(Ⅱ)得到五個一維鏈狀銅(Ⅱ)金屬錯合物及其單晶結構。 五個錯合物Complex(1)-(5)分別為： (1) [Cu(dione)(4,4’-bipy)]n(ClO4) (2) [Cu(L1) (μ-1,1N3)]n (3) [Cu2(L2)2(μ-1,1N3)(μ-1,3N3)]n (4) [Cu(PT)(CO2)(H2O)]n (5) [Cu2(BPP)2(μ-1,5 dca) (ClO4)]n HL1：(E)- 4-bromo-2-((2-(dimethylamino)ethylimino)methyl)phenol HL2：(E)-4-chloro-2-((2-(ethylamino)ethylimino)methyl)phenol 經由X-ray單晶繞射解析、元素分析、紅外線光譜及變溫磁化率(2-300K)等測定。錯合物(1)、(5)為反鐵磁性偶合作用，錯合物(1)之J = -1.15 cm-1、g = 2.00，錯合物(5)遵守Curie-Weiss law，經由計算得θ = -2.26 K；錯合物(2)-(4)為鐵磁性偶合作用，錯合物(2)之J = 4.99 cm-1、zJ’=-1.97 cm-1、g = 1.90，錯合物(3)之J = 4.98 cm-1、zJ’=-0.11 cm-1、g = 2.11，錯合物(4)之2J = 26.28 cm-1、zJ’=-0.12 cm-1、 g = 1.90。

Five 1-D Cu(II) complexes, [Cu(dione)(4,4’-bipy)]n(ClO4) (1), [Cu(L1) (μ-1,1N3)]n (2), [Cu2(L2)2(μ-1,1N3)(μ-1,3N3)]n (3), [Cu(PT)(CO2)(H2O)]n (4), [Cu2(BPP)2(μ-1,5 dca) (ClO4)]n (5), HL1：(E)- 4-bromo-2-((2-(dimethylamino)ethylimino)methyl)phenol HL2：(E)-4-chloro-2-((2-(ethylamino)ethylimino)methyl)phenol have been prepared with polydentate ligands and bridging ligand ( N3-,dca- ). The molecular structures of these complexes have been determined by single-crystal X-ray diffraction method, IR spectroscopy and element analysis. Variable temperture magnetic susceptibility data in the range of 2-300 K for 1 and 5 reveal the existence of weak antiferromagnetic interactions. Complex 1 shows J = -1.15 cm-1 , g = 2.00. Complex 5 obeyed the Curie-Weiss law withθ= -2.26 K. Complex 2-4 show weak ferromagnetic interactions, with J = 4.99 cm-1, zJ’=-1.97 cm-1, g = 1.90 for 2 ; J = 4.98 cm-1, zJ’=-0.11 cm-1, g = 2.11 for 3 ; and 2J = 26.28 cm-1, zJ’=-0.12 cm-1, g = 1.90 for 4.
