The Synthesis and Spectral Characterization of the Ternary Complexes of Rare-Earth with meta-Nitrobenzoic Acid
【摘要】 本文合成了稀土(RE=Nd,Sm,Tb,Gd)与间硝基苯甲酸(HL)、邻菲罗啉(phen)和稀土(RE=Nd,Sm,Tb,Gd)与间硝基苯甲酸(HL)、2,2-联吡啶(bipy)的三元固体配合物.通过元素分析、摩尔电导、红外光谱、紫外光谱、热分析等手段确定了稀土配合物的组成为REL3phen.nH2O(n=0,1)和REL3bipy.K.nH2O(n=2,4,).并对该类配合物的结构与性质进行了表征.
【Abstract】 The ternary rare_earth(RE=Nd,Sm,Tb) complexes containing meta-nitrobenzoic acid(HL) and phenanthroline(phen) or 2,2′-bipyridine(bipy) were obtained form ethanol solvent.Their chemical compositions were deduced to be REL-3·phen·nH-2O or REL-3·bipy·K·nH-2O(n=0,1,2,4) by the element analysis and molar conductivity.The properties of complexes were characterized and discussed using infrared and ultraviolet absorption spectra and DTA-TGA.
