摘要

本文以一级配体(联苯胺亚胺)(H2L)和二级配体(1,10-菲罗啉)(L′)与金属离子分别以1:2:2的摩尔比反应,合成了金属离子Fe(II)、Co(II)、Ni(II)和Cu(II)的双核金属配合物。采用CHN元素分析、FT-IR、UV-Vis、磁化率、摩尔电导率、1H NMR和TGA-DTA热重分析对配合物进行了表征。根据元素分析和光谱测量的结果,其中Fe(II)、Co(II)和Ni(II)配合物具有八面体几何形状,而Cu(II)配合物具有方形平面几何形状。所有制备的配合物均完全稳定,可保持数月而无明显变化。采用扩散琼脂平板法对制备的化合物对革兰氏阴性变形杆菌和克尔伯氏菌的抑菌活性进行了评价。孔周围的抑制带直径表明细菌对这些化合物的敏感性,其中克雷伯氏菌对这些化合物的敏感性高于变形杆菌。所有合成的配合物对克尔伯氏菌和Protea的作用均比抗生素(阿米卡星)更显著。

Synthesis, Characterization and Biological Activity of Mixed Ligand (Imine of Benzidine and 1,10-Phenanthroline) Complexes with Fe(II), Co(II), Ni(II) and Cu(II) Ions
In this paper, binuclear metal complexes of the metal ions Fe(II), Co(II), Ni(II) and Cu(II) were synthesized by the reaction of the primary ligand (imine of benzidine) (H2L) and the secondary ligand (1,10-phenanthroline) (L`) with these metal ions in a molar ratio of 1:2:2, respectively. The complexes were characterized using CHN elemental analysis, FT-IR, UV-Vis, magnetic susceptibility, molar conductivity, 1H NMR, and TGA-DTA thermogravimetric analysis. According to the results obtained from the elemental analysis and spectral measurements where complexes of Fe(II), Co(II) and Ni(II) have octahedral geometry, while the complex with Cu(II) has a square planar geometry. All the prepared complexes are wholly stable and can keep for months without any significant change. The antibacterial activities of the prepared compounds were evaluated with regard to two bacteria species, gram-negative Proteus and Kelbsiella, by using diffusion agar plates. The inhibition zone diameter around the holes indicated the sensitivity of the bacteria to these compounds, where the Klebsiella bacteria were revealed to be more highly sensitive to these compounds than Proteus bacteria. All synthesized complexes showed more significant effects against Kelbsiella and Protea than the antibiotic (Amikacin).
