【摘要】 本文合成了二种稀土与对硝基苯乙酸(HL)、2,2’-联吡啶(bipy)三元固体配合物,通过元素分析等手段确定了其配合物的组成为ReL3bipy·2H2O(RE=Eu、Tb)。用红外光谱、紫外光谱,对该类配合物的结构与性质进行了表征。红外谱表明配体以-COO-形式与中心离子配位,同时这一点也被自由配体和配合物的UV谱所证实。
【Abstract】 Two ternary solid complexes containing p-nitrophenylacetic acid(HL) and 1,2-bipyridine (2,2’-bipy) have been synthesized in this work.The chemical composition of the compounds were determined to be REL3(bipy)-H2O(RE = Eu,Tb) by the elemental analysis.The structure and property of the complexes have been characterized by IR and UV.IR shows the ligand coordinated to the center ions with a -COO- bidentate bridged mood.This has been also proved by the UV spectra of free ligand and complexes.
