摘　　要：为了研究稀土与赤霉素的相互作用及其生物效应,在乙醇溶液中合成了两种新型稀土(Sm,Dy)-赤霉素(GA3)配合物,并对其进行了元素分析、质谱、紫外光谱、红外光谱、差热分析等表征。结果表明:配合物的组成为RE(GA3-)2Cl.6H2O(RE:Sm3+,Dy3+),镝-赤霉素配合物的热稳定性略高于钐-赤霉素配合物的。所得的两种配合物均易溶于二甲基甲酰胺、二甲基亚砜、甲醇、乙醇,不溶于水和丙酮中。earth with In order to investigating interaction of gibberellin and their biological effect, rare the two new complexes of rare earth （ RE ： Sm3 ＋ , Dy3 with gibberellin （GA3 ） were synthesized in ethanol solution. The structures of the two complexes were characterized by UV-Vis, IR, MS, element analysis and DTA. The result showed that complex was RE （GA3-）2C1.6H20. The thermostabil- ity of dysprosium gibberelin complex was higher than the thermostability of samarium gibberelin complex. The rare earth complexes with gibberellin were soluble in dimethylformamide, dimethyl sulfoxide, methanol and ethanol, but they were insoluble in water and ace- composition of tone.
