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

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.
