2,2′-联喹啉-N,N′-二氧化物与硝酸钍固态配合物的合成及性质研究

SYNTHESIS AND CHARACTERIZATION OF SOLID COMPLEX OF THORIUM NITRATE WITH 2, 2'-BIQUINOLINE-N, N'-DIOXIDE

摘要: 在无水乙醇中制得2,2′-取喹啉-N,N′-二氧化物(BiqO_2)与硝酸钍的固态配合物Th_2(BiqO_2)_3(NO_3)_8。对配合物进行了元素分析,红外光谱、溶解性及摩尔电导、紫外光谱、荧光光谱、X光粉末衍射,差热-热重分析等性质的研究。实验结果表明,在配合物中有桥式和整合式两种类型的配体存在。

Abstract: The solid complex Th2(BiqO2)3(NO3)8(BiqO2 = 2.2'-biquinoline-N'N'-di-oxide)is prepared using ethanol as reaction medium. The complex is characterized by elemental analyses, IR and UV spectra, solubilities and molar conductance, fluorescence spectrum, X-ray powder diffraction, differential thermal analyses(DTA) and thermogravimetric(TG)analysis.The results show that BiqO2 are bonded to Th4+ in two different modes, i.e. bridging mode and chelating mode.
