中文摘要：

以席夫碱[N，N’，双（2，4-二羟基苯甲醛）缩邻苯二胺]（L）和邻菲罗啉为配体，与稀土金属离子配位合成了稀土席夫碱邻菲罗啉三元配合物REM（o—phen）2C1·2H20（M=La^3＋、Pr^3＋、Nd^3＋、Sm^3＋），并利用红外光谱、紫外可见光谱、元素分析和摩尔电导率仪对其结构进行了分析表征，同时将该类配合物应用于生物活性抑菌试验。结果表明，所有配合物对大肠杆菌、金黄色葡萄球菌和白色念珠菌都有较好的抑菌作用，且配合物RESm（o—phen）。C1·2H20的抑菌活性最好。

英文摘要：

Rare earth Schiff base and phenanthroline ternary complexes REM （o-phen）2C1·2H20（M=La3＋ , Pr^3＋, Nd^3＋, Sm^3＋） was synthesized with coordinate reaction containing Schiff base, phenanthroline and rare earth ion. Those complexes were characterized with infrared spectroscopy （IR） and UV-visible spectroscopy. To investigate the antibacterial activities of those ternary complexes, all of them were applied to against Escherich coli, Staphy lococ- cusaureus, Candida albican. The results showed that all of the complexes have higher antibacterial ability for three bacteria, and the complex RESm（o-phen）2 C1·2H20 have the optimal antibacterial ability in these complexes.
