苯甲酸系列邻菲啰啉硝酸根稀土四元混配配合物的合成、表征和抗菌活性研究

Study on synthesis,characterization and antibacterial activity of quaternary mixed complexes [L n(C_6H_5COO)_2(NO_3)(phen)]_2 and [Nd(x-MBA)_2(NO_3)(phen)]_2

在酸性介质 ,乙醇 /水混合溶剂中合成得到了四元混配配合物 [Ln(C6 H5COO) 2 (NO3)(phen) ]2 (Ln =La ,Ce ,Pr ,Nd ,Sm ,Eu ,Gd ,Er ,Tm)和 [Nd(x MBA) 2 (NO3) (phen) ]2 (x =o、p、m) (MBA =甲基苯甲酸 )。用元素分析、IR和UV方法对配合物进行了表征 ,并对配合物的抗枯草杆菌、大肠杆菌、金黄色葡萄球菌、酵母菌、白念珠菌、和霉菌的性能进行了研究。

Quaternary rare earth complexes [L n(C 6H 5COO) 2(NO 3)(phen)] 2(Ln =La, Ce, Pr, Nd, Sm, Eu, Gd, Tm,Er) and [Nd(x-MBA) 2(NO 3)(phen)] 2(x=o、p、m) were synthesized in ethanol/water solution system with slight acidity, the products were characterized by elemental analysis, IR. Their antibacterial activity were examined. Some of them gave considerable good results.
