指導教授 : 陳志德

摘要


經由過渡金屬化合物CuCl2, CuBr2 及Cu(ClO4)2 與配位基 N,N'-bis(2-pyridinyl)-1,4-benzenedicarboxamide (L1) 的反應,得到了 Cu2Cl4(L1)(DMSO)2 · 2DMSO, 2, Cu2Br4(L1)(DMSO)2 · 2DMSO, 3 與[Cu2(L1)(DMSO)6](ClO4)4 · 2DMSO, 4 以 HgCl2, HgBr2 及 Cd(NO3)2, 與配位基N,N'-bis(2-pyrimidinyl)-1,4-benzenedicarboxamide (L2) 的反應得到了Hg2(L2)Cl4, 7, {Hg(L2)Br2 · H2O}∞, 8, {[Cd(L2)(NO3)2] · 2DMF}∞, 9 此六個錯化合物的構造均已利用 X-ray 鑑定之。化合物 2 和 3 形成雙核的金屬化合物,而分子間 是經由 N-H---O 和 C-H---X (X = Cl, Br) 的氫鍵作用力所連接起 來。錯化合物 4 亦為雙核的金屬錯化合物,而分子間是經由 N-H---O 和 C-H---O 的氫鍵作用力所連接起來。化合物 7 形成雙 核的金屬錯化合物,而每個分子是經由 N-H---Cl 和 C-H---Cl 的氫 鍵作用力所連接起來。錯化合物 8 形成鋸齒狀的長鏈,每條長練 是經由 C-H---Br 和 C-H---O 的氫鍵作用力所連接起來。錯化合物 9 形成鋸齒狀的長鏈,每條長練是經由 N-H---O 和 C-H---O的氫 鍵作用力所連接起來。

並列摘要


A series of the transition metal complexes Cu2Cl4(L1)(DMSO)2 · 2DMSO, 2, Cu2Br4(L1)(DMSO)2 · 2DMSO, 3, [Cu2(L1)(DMSO)6](ClO4)4 · 2DMSO, 4, Hg2(L2)Cl4, 7, {Hg(L2)Br2 · H2O}∞, 8, and {[Cd(L2)(NO3)2] · 2DMF}∞, 9, where L1 = N,N'-bis(2-pyridinyl)-1,4-benzenedicarboxamide; L2 = N,N'-bis- (2-pyrimidinyl)-1,4-benzenedicarboxamide, have been prepared by the reactions of transition metal compounds CuCl2, CuBr2, Cu(ClO4)2, HgCl2, HgBr2, and Cd(NO3)2 with L1 and L2. All the complexes have been structurally characterized by X-ray crystallography, confirming that 2 - 4 and 7 are binuclear complexes, and 8 - 9 are coordination polymers. Complexes 2 and 3 form binuclear complexes which are interlinked through a series of S---S interactions and C-H---X (X = Cl, Br) hydrogen bonds. Complex 4 forms binuclear complexes which are interlinked through a series of N-H---O and C-H---O hydrogen bonds. Complex 7 forms binuclear complexes which are interlinked through a series of N-H---Cl and C-H---Cl hydrogen bonds. Complexes 8 and 9 form zigzag chains, where the molecules of complex 8 are interlinked by C-H---Br hydrogen bonds and those of complex 9 are interlinked by a series of N-H---O and C-H---O hydrogen bonds.
