三氟乙酰丙酮钕与冠醚的混配配合物的合成与表征

Synthesis and characterization of mixed ligand complex of neodynium trifluoro acetylacetonate and crown ether

本文首次合成了三氟乙酰丙酮、二苯并18冠6与钕的混配配合物,对合成方法进行了研究,并以元素分析、红外光谱、反射光谱及热分析等方法对配合物进行了表征,结果表明配合物组成为Nd(TFA)_3·DB18C6,两种配体均直接与钕离子配位。

A new mixed ligand complex of neodynium trifluoroacetylacetonate and crown ether has been synthesized for the first time. Elemental analysis and molar conductance measurement show that the composition of the complex is Nd(TFA)3·DB18C6. IR and reflection spectra and thermoanalysis of the complex indicate that some oxygen atoms in both TFA-and DB18C6 are directly coordinated with Nd3+. The properties of the complex affected by β-diketone are discussed in the paper.
