摘要:

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.

关键词: 肼, 硫酸根, 亚铁离子, 反铁磁交换作用, 磁有序

Abstract:

A novel transition metal iron(II) sulfate containing hydrazine (N2H4) ligand: [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.

Key words: Hydrazine, Sulfate group, Ferrous ion, Antiferromagnetic interaction, Magnetic ordering
