【摘要】在95%乙醇溶液中合成了3种稀土萘甲酸邻菲罗啉三元配合物,其通式为RE(Nap)3·phen(RE=La3+,Eu3+,Tb3+;Nap=萘甲酸根;phen=邻菲咯啉).并用元素分析、IR、1H NMR、XPS、XRD等分析手段对产物进行了表征,结果表明萘甲酸根以双齿方式与稀土离子配位.更多还原

【Abstract】 Three new complexes of rare earth with αnaphthoic acid (HNap) and 1,10phenanthroline(phen) were prepared in 95% alcohol solution. These complexes are all of the composition of RE(Nap)3·phen(RE=La,Eu,Tb).Their composition and properties were investigated by elemental analysis,IR spectra,1HNMR、XPS、XRD. Results suggest that the carboxylate ions in αnaphthoate take the bidentate coordination modes.更多还原
