摘要

利用N,N'-二-(4-吡啶甲基)己二醯二胺(L)，與雙羧酸角型配位基搭配Co(Ⅱ)金屬鹽類以水熱法可合成出三種化合物：{[Co2(L)0.5(FIPBB)2(H2O)]•2H2O•CH3OH}n [H2FIPBB = 4,4′-hexafluoroisopropylidenebis(benzoic acid)]，1 {[Co(L)(OBA)•H2O]}n (H2OBA = 4,4-oxybis benzoic acid)，2，與{[Co(OBA)2(H2O)2]}n, 3。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{44.62}{44.66}2 拓譜學的三維結構。化合物2為具有sql 拓譜學的二維結構，且具有多聚鏈鎖。化合物3具有sql 拓譜學的二維結構。化合物2與3間的結構轉換亦加以探討。

Reactions of N,N'-bis(4-pyridylmethyl)adipoamide (L) with the angular dicarboxylic acids and Co(II) salts afforded {[Co2(L)0.5(FIPBB)2(H2O)]•2H2O•CH3OH}n [H2FIPBB = 4,4′-hexafluoroisopropylidenebis(benzoic acid)], 1, {[Co(L)(OBA)•H2O]}n (H2OBA = 4,4-oxybis benzoic acid), 2, and {[Co(OBA)2(H2O)2]}n, 3, which have been structurally determined by using single-crystal X-ray diffraction and characterized by using powder X-ray diffraction, elemental analysis, thermal gravimetric analysis and infrared spectra. While complex 1 exhibits a 3D framework with the {44.62}{44.66}2 topology, complex 2 forms a polycatenated 2D net with the sql topology and complex 3 shows a 2D layer with the sql topology. Structural transformations between complexes 2 and 3 are also discussed.
