摘　　要：金属-有机框架(Metal-Organic Frameworks,MOFs)是一类新兴的晶体多孔材料,具有易于设计的结构、可调节的功能、高孔隙率和超大比表面积等特性,受到研究者们的广泛关注。采用溶剂热方法,选用异烟酸(HINA)和氯化铁(FeCl3)为原料,合成了一例新的基于混合价态的三核[Fe^(Ⅱ)Fe^(Ⅲ)_(2)]簇为SBU的三维中性框架结构,即[Fe^(Ⅱ)_(2) Fe^(Ⅲ)_(4)(μ_(3)-O)_(2)(H_(2)O)(INA)_(12)]·4H_(2)O·2NMF(命名为化合物1,其中NMF为N-甲基甲酰胺),并对化合物1进行了单晶X射线衍射、粉末X射线衍射、红外光谱、热重等表征。此外,还研究了化合物1的磁性性能。Metal-Organic Frameworks(MOFs)are a new class of crystalline microporous materials that have attracted extensive attention due to their easy-to-design structures,adjustable functions,high porosity,and large specific surface area.In this paperwork,a novel three-dimensional neutral frame structure based on mixed valence state was solvothermally prepared by the reaction of isonicotinic acid(HINA)andferric chloride(FeCl_(3))as raw materials,[Fe^(Ⅱ)_(2) Fe^(Ⅲ)_(4)(μ_(3)-O)_(2)(H_(2)O)(INA)_(12)]·4H_(2)O·2 NMF(named compound 1,where NMF is N-methylformamide).Compound 1 was further characterized by single crystal X-ray diffraction,powder X-ray diffraction and infrared spectroscopy,thermogravimetric analysis and magnetism.
