雙醯胺雙吡啶異構物對二價鎘配位高分子結構多樣性之研究
Isomeric Effect of N,N’-Bis(pyridylmethyl)oxalamide on the Structural Diversity of Cd(Ⅱ) Coordination Polymers
摘要
利用N,N'-二-(3-吡啶甲基)乙二醯二胺(L1)，N,N'-二-(4-吡啶甲基)乙二醯二胺(L2)，與三羧酸配位基搭配Cd (Ⅱ)金屬鹽類以水熱法可合成出二種化合物：{[Cd(L1)(1,3,5-HBTC)(H2O)]·3H2O}n，1與{[Cd(1,3,5-BTC)(H2O)]·(H2L2)0.5·3H2O}n ， 2。這些化合物已利用單晶X-ray繞射儀、粉末X-ray繞射儀、元素分析儀、紅外線光譜儀與螢光光譜儀加以鑑定，並使用熱重分析儀來研究其熱穩定性。化合物1為具有2,2,4C1 拓譜學的二維結構。化合物2為具有sra 拓譜學的三維結構。

Hydrothermal reactions of N,N’-di(3-methylpyridyl)oxalamide (L1), N,N’-di(4-methylpyridyl)oxalamide (L2), and tricarboxylic acid with Cd (Ⅱ) salts in ethanol afforded two divalent coordination polymers, {[Cd(L1)(1,3,5-HBTC)(H2O)]·3H2O}n (1,3,5-H3BTC = benzene-1,3,5-tricarboxylic acid), 1, and {[Cd(1,3,5-BTC)(H2O)]·(H2L2)0.5·3H2O}n, 2, which have been structurally characterized by using single crystal X-ray diffraction, powder X-ray diffraction, elemental analyses, infrared spectrometer and fluorescence spectrometer. Complex 1 forms a 2D framework with 2,2,4C1 topology, while complex 2 shows a 3D framework with the sra topology. Their thermal and luminescent properties have also been investigated.
