邻菲罗啉单氮氧化物与钪(Ⅲ)钇(Ⅲ)配合物的合成与性质

SYNTHESES AND CHARACTERIZATION OF COMPLEXES OF 1,10-PHENANTHROLINE-N-OXIDE WITH Sc(III) AND Y (III)

邻菲罗啉单氮氧化物(PhenNO),分子内存在较大的共轭π键,对过渡金属离子具有良好的配位性能,其中某些配合物具有荧光。迄今为止,Sc、Y与该配体的配合物尚未见文献报道。本文在非水介质中合成出Sc(Ⅲ)、Y(Ⅲ)盐与PhenNO的五个新配合物,研究了它们的组成及其有关性质。由于Sc(Ⅲ)和Y(Ⅲ)的离子半径不同,它们的配位行为及其配合物的性质应有差异,试验结果证实了预测的结果。

Five new complexes of Sc(III) and Y (III) salts with 1,10-phenanthroline-N-oxide (PhcnNO) having the compositions M(PhenNO)3Cl3, M(PhenNO)4(SCN)3 and Y(PhcnNO)(acac)3(M = Sc, Y; acac = acetylacetonate anion ) were synthesized. The complexes were characterized by TG-DSC, IR spectra, fluorescence spectra and molar conductance. The difference in the properties of the complexes of Sc(III) and Y(III) salts was discussed in this paper.
