配合物La(C_6H_5CHOHCOO)_3(phen)(H_2O)的合成

Synthesis and Characterization of the Complex La(C_6H_5CHOHCOO)_3(phen)(H_2O)

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（ C6H5 CHOHCOO ） 3 （phen） （ H2O ） was synthesized starting from mandelic acid, 1,10- phenanthroline and nitrate of rare earth. Through elemental analysis, IR and ^1H-NMR, its composition and structure were confirmed, and its thermal property were characterized with TGA. The results showed that the 1,10-phenanthroline acts as a bidentate ligand and carboxylic groups in the complex coordinate to the rare earth ions in the form of a bridge or monodentate ligand.
