双核金属配合物的配位活性与催化活性比单核金属配合物要高，其结构也比单核金属配合物要复杂，因此设计合成双金属配合物的难度大大增加。本实验旨在设计一个合成双金属配合物的化学基础实验，对学生的思维创新进行培养、让学生综合专业理论知识和实践操作能力、同时培养学生面对问题时能够对其进行分析并解决的能力，提升科研水平。本实验结合草酸根离子、乙二胺都是良好 的双齿配体，Fe(Ⅲ)、Zn(Ⅱ)、Co(Ⅱ)能与其形成相应的金属配合物的特点，以草酸根离子、乙二胺为配体，展开Zn(II)-Fe(III)异核金属配合物、Co (II)-Fe(III)异核金属配合物的合成探究，并探索温度、试剂对合成的影响，通过ICP、红外光谱、核磁氢谱三种方法对产物进行表征，通过对比ICP百分比含量、红外光谱对比，发现最终合成产物为Zn-乙二胺配合物和Co-乙二胺配合物。

The coordination activity and catalytic activity of the binuclear metal complex are higher than that of the mononuclear metal complex, and the structure is also more complicated than the mononuclear metal complex. Therefore, the difficulty in designing and synthesizing the bimetallic complex is greatly increased. This experiment aims to design a chemical basic experiment for the synthesis of bimetallic complexes, to train students' thinking innovation, to enable students to integrate professional theoretical knowledge and practical operation ability, and to train students to analyze and solve problems in the face of problems. Ability to improve the level of research.In this experiment, oxalate ion and ethylenediamine are good bidentate ligands, and Fe(III), Zn(II) and Co(II) can form corresponding metal complexes with oxalate ion and B. The diamine is a ligand, and the synthesis of Zn(II)-Fe(III) heteronuclear metal complexes and Co(II)-Fe(III) heteronuclear metal complexes is explored, and the effects of temperature and reagents on the synthesis are explored. The products were characterized by ICP, IR and NMR. The final synthesis products were Zn-ethylenediamine complex and Co-ethylenediamine complex by comparing the percentage of ICP and infrared spectrum.
