用苯羟基乙酸、邻菲罗啉与稀土的硝酸盐为原料合成了配合物La(C_6H_5CHOHCOO)_3(phen)(H_2O),通过元素分析、红外光谱、核磁共振等测试手段,确定了配合物的组成和结构,并通过热重分析对其热性质进行了表征。结果表明,配合物中邻菲罗啉以双齿螯合方式配位,而苯羟乙酸则以桥联或单齿方式参与配位。
The complex La (C_6H_5CHOHCOO) _3 (phen) (H_2O) was synthesized by using phenylacetic acid, phenanthroline and rare earth nitrate as the starting materials. The content of the complex was determined by elemental analysis, infrared spectroscopy and nuclear magnetic resonance Composition and structure, and its thermal properties were characterized by thermogravimetric analysis. The results showed that the phenanthroline complexed with bidentate chelate, while the phenylacetate acted as a bridging or monodentate ligand.
