中文摘要:
      本文采用分步法,首先合成了新的多齿Schiff碱仲胺配体N,N’-双(2-羟基苯甲醛仲胺基乙基)-2,6-吡啶二甲酰胺(L),进一步合成了5个新的过渡金属配合物,再通过元素分析、红外光谱、紫外光谱及核磁共振等测试手段对配体及配合物进行了表征和合理的结构推测;并采取微量稀释法研究了它们对大肠杆菌的抑菌活性。结果表明:当配体与Co和Zn离子配位后,对大肠杆菌抑菌效果明显增强。
英文摘要:
      In this paper, we took fractional steps to synthesize linear multidentate Schiff base amine ligand [N,N-bis(2-dihydroxyphenyl-amidoethyl)-2,6-pyridinedicarboxylic diamide (L)] firstly, then the 5 new transition metals complexes linked by Shiff base amine. The ligand and complexes are characterized by elemental analysis, IR, UV-VIS and IH NMR. And also the rational structures of them are speculated.The inhibitory activities of compounds on Escherichia coli were studied by micro- dilution. The results appear that Co and Zn complexes show good inhibitory effect on Escherichia coli.
