糠醛缩邻氨基苯甲酸Schiff碱稀土配合物的合成与表征

Synthesis and characterization of Schiff base derived from furfural and anthranilic acid and its rare earth complexes

合成了糠醛缩邻氨基苯甲酸Schiff碱及其4种稀土配合物,并通过元素分析、IR、UV、1H NMR和热失重分析对其组成和结构进行表征,结果表明,配体是以四齿的形式参与配位,配位数为8,配合物的组成为Re(L)2.2.5H2O(Re=Eu、Sm、La、Y)。

Schiff base derived from furfural with anthranilic acid and its four rare earth complexes were synthesized and characterized by elemental analysis,IR,UV,1H NMR and thermo-gravimetric analysis.The results indicated that the Schiff base acted as a quadridentate ligand and the coordination numbers were 8,the composition of complexes was Re（L）2·2.5H2O（Re=Eu,Sm,La,Y）.
