| 摘 要： | 在pH=6～7的乙醇-水溶液中,合成了9个1-苯基-3-甲基-5-氧代吡唑-4-基乙醛酸稀土配合物。元素分析确定了配合物的组成为Ln_2A_3·H_2O(Ln=La,Pr,Nd,Sm,Eu,Tb,Er,Yb和Y,A为配体)。通过摩尔电导,紫外光谱、红外光谱,核磁共振谱以及差热分析对配合物进行了表征,认为配体为四齿配体,配合物具有双核结构。

| Abstract: | Nine rare earth complexes, Ln_2A_3·H_2O(where A=1-phenyl-3-methyl-5-pyrazolone-4-glyoxalic acid, Ln=La, Pr, Sm, Eu, Nd, Tb, Er, Yh and Y) have been prepared by the reaction of H_2O with the relative rare earth nitrate in the ethanol-water solution of pH=6～7. The compounds were characterized by elemental analysis, molar conductance, ultraviolet,infrared,proton magnetic resonance spectroscopic and thermogravimetrie analysis studies. On the basis of the above investigation,it can be considered that H_2A is tetradentate ligand and the complexes are binuclear structure. |
