[Fe(N2H5)2(SO4)2]n的合成、结构和磁性质(英文)

Synthesis,Structure and Magnetic Properties of Iron(Ⅱ) Sulfate Containing Hydrazine

采用水热合成方法得到一例新的过渡金属铁(Fe)的含肼硫酸盐:[Fe(N2H5)2(SO4)2]n(1).用单晶X射线衍射的方法对其晶体结构进行了表征.结果表明,该化合物以硫酸根为桥连配体,质子化的肼分子为端基配体,形成一维(1D)链状结构.肼分子和硫酸根形成的链间氢键,将1D链进一步扩展成三维(3D)结构.磁性测试表明化合物在低温下显示出反铁磁有序的磁行为.

A novel transition metal iron（Ⅱ） sulfate containing hydrazine（N2H4）,[Fe（N2H5）2（SO4）2]n（1）,is prepared by a hydrothermal method.Single-crystal X-ray diffraction reveals that 1 consists of onedimensional（1D） sulfate-bridged homometallic chains with protonated hydrazine molecules as terminal ligands.Hydrogen bonds between protonated hydrazine and sulfate ions connect the chains into a threedimensional（3D） extended framework.Magnetic measurements indicate that 1 exhibits the antiferromagnetic ordering behavior at low temperature.
