Synthesis,characterization and antibacterial activity of ternary lanthanide complexes

Ternary complex was prepared from lanthanum chloride,Schiff base and phenanthroline.Its composition was characterized by elemental analysis,UV-Vis,FTIR and TEM.The composition of the ternary complex was confirmed to be La(L)phen(NO3)3C2H5OH · CH3OH.The antibacterial activity test results showed that the complex exhibited antibacterial ability against escherichia coli and staphylococcus aureus,and antibacterial cycle diameter of ternary complex was 26 mm and 20 mm,and minimal inhibitory concentration was 60 mg/L and 130 mg/L.The ternary complex exhibited better antibacterial activities against E.coli.
