二茂铁基甲酰丙酮与三价希土金属反应、合成了十二个含二茂铁基的希土螯合物。元素分析结果表明螯合物的一般组成为 (C_5H_5FeC_5H_4COCHCOCH_3)_3Ln·xH_2O, 当Ln=La时,x=2;当Ln=Y、Nd、Sm、Eu、Gd、Dy、Ho、Er、Tm、Yb、Lu时,x=1。螯合物在质谱中出现去结晶水后的分子离子峰。通过红外光谱证实了螫合物的结构,紫外光谱测定的结果表明,二茂铁基甲酰丙酮位于306nm处的K吸收带在螯合物中红移至313～314nm。运用TG—DTA法核实了螯合物中结晶水的个数,并测得了螯合物的热分解温度。
Ferrocenyl formyl acetone reacted with trivalent earth metal to synthesize twelve ferrocenyl-containing rare earth chelates. Elemental analysis shows that the general composition of the chelate is (C_5H_5FeC_5H_4COCHCOCH_3) _3Ln · xH_2O, x = 2 when Ln = La; when Ln = Y, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb , Lu, x = 1. Chelates have molecular ion peaks after de-crystallized water appears in the mass spectrum. The structure of the complex was confirmed by infrared spectroscopy. The results of UV spectrophotometry showed that the K absorption band of ferrocenylformylacetone at 306 nm red-shifted to 313 ~ 314 nm in the chelate. The number of crystal water in the chelate was verified by TG-DTA method and the thermal decomposition temperature of the chelate was measured.
