In the third chapter, eight new complexes of 4, 6-dimethylpyrimidine 2-thioacetic acid with rare earth metals has been synthesized and characterized by means of elemental analysis, molar conductivity, IR,〓 NMR and TG-DTA. The general formula of the complexes is Ln〓(n=4 or 5). In the complexes, the deprotonated ligand coordinated to the rare earth metal ions in chelate bidentate mode. 4 or 5 molecular of crystal water existed in the complexes.

第三章合成了八种4，6-二甲基嘧啶-2-硫代乙酸的稀土配合物，通过元素分析、摩尔电导、红外光谱、核磁共振氢谱和热重-差热对配合物进行了表征，研究结果表明，配合物的组成为Ln〓n=4或5），在配合物中配体羧基脱去质子后采用螯合双齿的方式与稀土离子形成配位键，同时，配合物中含有4或5个结晶水。
