摘　　要：本研究合成了以烟酸、1,10-二氮杂菲为配体,以镱、镧为中心的稀土配合物。采用元素分析、摩尔电导、红外光谱、紫外光谱、荧光光谱、差热热重分析手段进行表征,并研究了三元配合物对常见细菌E.coli和S.aureus、真菌A.niger的抑菌活性。结果表明,合成的三元配合物的抑菌活性较配体均有提高。Two kinds of ternary complexes of rare earth, with 1,10-phenanthroline and nicotinic acid were synthesized firstly, and investigated using molar conductance, IR, UV, fluorescence spectroscopy and differential thermal gravimetric analysis methods. The antibacterial and antifungal activity of ternary complexes against bacteria （E.coli, S.aureus）, fungi （A.niger） were observed in vitro. Results show that the antibacterial and antifungal activity of ternary complexes was improved compared with ligand.
