镧系元素与邻菲咯啉单氮氧化物及乙酰丙酮三元配合物的研究

Study on the Ternary Coordination Compounds of Lanthanide Elements with 1, 10-Phenanthroline-N-oxide and Acetylacetone

本文合成十三种镧系元素与邻菲咯啉单氮氧化物(PhenNO)及乙酰丙酮(Hacac)的三元配合物。元素分析确定配合物的组成为Ln(PhenNO)(acac)_3(Ln=La,Pr,Nd,Sm—Lu)。对该系列配合物的红外光谱、紫外光谱、荧光光谱、热谱及电导等性质进行了研究。Sm(PhenNO)(acac)_3的X射线单晶结构分析表明,金属离子与三个acac及一个PhenNO的七个氧一个氮原子配位。配位数为八,配位多面体为变形十二面体。

Thirteen new ternary coordination compounds of lanthanide with 1, 10-phenanthroline-N-oxide (PhenNO)and acetylacetone (Hacac) with the general formula Ln (PhenNO) (acac)_3(Ln=La, Pr, Nd, Sm—Lu) have been prepared and characterized by elemental analysis, IR spectra, UV spectra, Fluorescence spectra, molar conductance, TG and DSC. The result of the single-crystal X-ray structure analysis for Sm (PhenNO) (acac)_3 shows that metal ion is eight-coordinated, being bonded to six acetylacetonate oxygen atoms and the oxygen atom and nitrogen atom from the 1, 10-phenanthroline-N-oxide, in the form of a distorded dodecahedron.
