乙二胺水杨醛双Schiff碱Cr(Ⅲ)配合物的合成与表征

摘要

以水扬醛与乙二胺为原料合成乙二胺水扬醛双Schiff碱,并进一步与Cr(Ⅲ)络合得到金属配合物；采用元素分析、紫外可见吸收光谱、红外光谱对乙二胺水杨醛双Schiff碱及其Cr(Ⅲ)配合物的结构进行了表征.结果表明,合成的乙二胺水杨醛双Schiff碱配体及其Cr(Ⅲ)配合物的分子结构与理论结构相符；乙二胺水杨醛双Schiff碱配体及其Cr(Ⅲ)配合物均有一定的抗茵活性,且Cr(Ⅲ)配合物的抗茵活性更好.%The ligand of salicylaldehyde-ethylenediamine double Schiff base was synthesized by Schiff base reaction using ethylenediamine and salicylaldehyde as raw materials. The metal complex was prepared by com-plexing Cr(Ⅲ) with the double Schiff base. The structure of ligand and Cr(Ⅲ) complex were characterized by elemental analysis,UV-Vis absorption spectrum,and IR spectrum. The results proved that the structure of ligand and Cr(Ⅲ) complex conformed with the target construction. The double Schiff base and its Cr(Ⅲ) complex both had antibacterial activity,and the complex had the stronger activity.
