摘要
本文研究了醋酸钴(II)与N,N-二甲基甲酰胺(DMF)中2-碘对苯二甲酸和1,10-菲罗啉(phen)的相互作用。该反应生成了两种产物:六烷基- (N,N-二甲基-甲酰胺- β o)钴(II)双-(碘化物)(化合物1)和MOF [Co(TP)(phen)·2DMF·2H2O](化合物2),其中TP为对苯二甲酸乙二醇酯。化合物1在单斜空间群Р2 1/ r中结晶,胞元参数a = 14.2974(4) Å, b = 10.7983(4) Å, c = 20.6437(9) Å, V = 3183.23 Å3。采用元素分析、红外光谱、x射线衍射、扫描电镜、热重法和体积氮吸附/脱附法对MOF进行了表征。样品具有永久孔隙和大表面积的微孔结构,对应于吸附型i。MOF的热分解形成氮掺杂碳纳米材料Co/CoO@C。
Study of the Products of the Interaction of Cobalt(II) Acetate with 2-Iodoterephthalic Acid and 1,10-Phenanthroline
A B S T R A C TIn the present work, the interaction of cobalt(II) acetate with 2-iodoterephthalic acid and 1,10-phenanthroline (phen) in N,N-dimethylformamide (DMF) was studied. The reaction leads to the formation of two products: hexakis(N,N-dimethylformamide-κO)cobalt(II) bis(iodide) (compound 1) and MOF [Co(TP)(phen)·2DMF·2H2O] (compound 2), where TP is terephthalate dianion. Compound 1 crystallizes in the monoclinic space group Р2 1/с with cell parameters a = 14.2974(4) Å, b = 10.7983(4) Å, c = 20.6437(9) Å, V = 3183.23 Å3. The MOF was characterized by elemental analysis, infrared spectrometry, X-ray diffraction, scanning electron microscopy, thermogravimetry and volumetric nitrogen adsorption/desorption. The sample has permanent porosity and a microporous structure with a large surface area corresponding to the adsorption type I. Thermolysis of MOF leads to the formation of nitrogen-doped carbon nanomaterials Co/CoO@C.
