摘要
丙酮酸在生物体内具有生理功能,它与稀土的二元配合物巳有报导。近期的研究结果表明某些稀土的邻菲咯啉三元配合物有一定的抑菌能力。本文报道丙酮酸(pyr-H)、邻菲咯啉(phen)稀土三元固体配合物的合成与表征结果。 按硝酸稀土:邻菲咯啉:丙酮酸(摩尔比)=1:1:3,将一定量的硝酸稀土加入无水乙醇中,溶解完全后,加入计算量丙酮酸,加热搅拌半小时。
Five ternary complexes of rare earths (RE = La, Ce, Nd, Eu and Gd) with pyruvic acid(pyr) and o-phenanthroline (phen) were prepared. The chemical compositions of the comple-xes obtained were ascertained by elemental and chemical analysis as RE_2 (phen)_3(pyr)(NO_3)_5, IR and Raman spectra, molar conductances, X-ray diffraction analysis, thermalanalys's of these complexes were also studied.
