摘　　要：该实验通过前驱体法制备了一个七核铁配合物(Fe_(7)),并对其进行了X-射线单晶衍射、红外光谱、X-射线粉末衍射和磁性表征。实验结果表明,Fe_(7)内Fe^(3+)之间存在反铁磁耦合作用,且Fe_(7)有弱的交流磁化率虚部信号。该实验可以帮助学生理解“结构化学”课程中的重难点,掌握配合物的合成与单晶培养方法,了解相关大型仪器的使用方法,并通过化学软件表达配合物的结构与性质,有助于他们科学素养的养成。This experiment prepared a heptanuclear iron complex(Fe_(7)) by employing the precursor method,and the complex was characterized by X-ray single-crystal diffraction,infrared(IR) spectrum,powder X-ray diffraction and magnetic properties.The results indicated that the weak antiferromagnetic interactions between Fe^(3+) ions in the Fe_(7)complex are presented,and the Fe_(7)complex exhibits the weak out-of-phase signals of ac magnetic susceptibilities.The experiment can help students understand some emphases and difficulties in the structural chemistry,master the methods of the complex synthesis and single crystal growths,know the operating methods of the large-scale instruments,and express the structures and properties of complexes by employing some kinds of software,which can further cultivate the students’ scientific literacy.
