A series of complexes of the type [$ML_2Cl_2$], where L=2-(o-anisylidene-2'-imino) amino benzimidazole (AIAB) and 2-(furfurylidene imino) amino benzimidazole (FIAB), M=Cu(II), Co(II), Ni(II) and Zn(II), have been synthesized and characterized on the basis of elemental analysis, thermal analysis, molar conductivity, magnetic moment, electronic, infrared, $^1H$-NMR spectral studies. The results are in consistent with bidentate chelation of ligand with azomethine nitrogen and ring nitrogen donors. All these Schiff bases and their complexes have also been screened for their antibacterial (Bacillus subtilis, Bacillus stearothermophilus, Escherichia coli and Salmonella typhi) and antifungal activities (Aspergillus niger and Aspergillus flavus).
合成了一系列类型为 [ML₂Cl₂] 的络合物,其中 L=2-(o-乙苯基亚氨基)-2'-氨基苯并咪唑 (AIAB) 和 2-(呋喃基亚氨基)氨基苯并咪唑 (FIAB),M=Cu(II)、Co(II)、Ni(II) 和 Zn(II)。这些络合物通过元素分析、热分析、摩尔电导率、磁矩、电子、红外和 ^1H-NMR 谱学研究进行了表征。结果与配体通过亚胺氮原子和环氮原子双齿螯合一致。所有这些施夫碱及其络合物还进行了抗菌(枯草芽孢杆菌、嗜热芽孢杆菌、大肠杆菌和伤寒沙门氏菌)和抗真菌活性(黑曲霉和黄曲霉)的筛选。
