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,然后慢慢加入含计算量邻菲咯啉的 Pyruvate has physiological functions in the body, and its binary complex with rare earth has been reported. Recent research results show that some rare earth phenanthroline ternary complexes have some antibacterial ability. This paper reports the synthesis and characterization of pyr-H, phenanthroline ternary complexes. According to the rare earth nitrate: phenanthroline: pyruvic acid (molar ratio) = 1: 1: 3, a certain amount of rare earth nitrate is added to the anhydrous ethanol, after the dissolution is complete, the calculated amount of pyruvic acid is added and the mixture heated for half an hour, Add the calculated amount of orthophenanthroline slowly
