摘要
离子液体是一种在近室温下为液态的以阴阳离子配伍形式存在的离子型化合物。离子液体由于其低熔点、高沸点、易成模的特点被广泛应用在化学合成、电化学及分析化学等相关领域。本文使用1-乙基-3-甲基咪唑溴盐离子液体~[Emim]Br作为溶剂和结构导向剂合成出两种亚磷酸铁开放骨架化合物,其中三维пшFe_2Fe(NH_4)(HPO_3)_4(JUI-1,Jilin University Ionothermal synthesis-1)结晶于P21/c单斜空间群,其晶胞参数为:a=12.4?,b=10.2?,c=9.3?,β=100.1?;Fe_2(HPO_3)_3(JUI-2)结晶于六方P63/m空间群,其晶胞参数为:a=b=8.0?,c=7.3?,γ=120?。我们对其进行了红外光谱、热重分析、穆斯堡尔谱及磁性等测试。其中JUI-1具有特殊的亚铁磁性,在感温电磁器件开关方面具有良好的应用前景;JUI-2具有反铁磁性。
Ionic liquids are a class of organic molten salts,which are completely constituted by the ions at room temperature and adjacent temperature.The compounds possess negligible vapor pressure,high boiling point and it can improve the templating effect,which have been widely used in chemical synthesis and other related fields.In this work,two iron phosphites open-framework have been synthesized via ionothermal method by using1-Ethyl-3-methylimidazolium bromide([Emim]Br) as the solvent.The Fe_2~ⅡFe~Ⅲ(NH_4)(HPO_3)_4(JUI-1,Jilin University Ionothermal synthesis-1) crystallizes in the monoclinic P2_1/c space group with unit-cell parameters a=12.4A,b=10.2A,c=9.3A,β=100.1°;the Fe_2(HPO_3)_3(JUI-2) crystallizes in the hexagonal P6_3/m space group with unit-cell parameters a = b = 8.0A,c=7.3A,γ=120°.The compounds have been characterized by infrared analysis,thermogravimetric,Mossbauer analysis and magnetic analysis,which show diffrerent magnetic behavior.
