目的:研究苯并咪唑类化合物结构与性质之间的关系,探讨具有抗菌性质新型苯并咪唑类配合物材料的合成方法。方法:溶剂热条件下,硝酸钴、硝酸镍与4,4’-二(苯并咪唑-1-甲基)联苯(bbmb)和间苯二甲酸(IPA)的自组装生成2个新型配合物{[Co(bbmb)(IPA)]·(H_2O)_3}_n(1)和{[Ni(bbmb)(IPA)(H_2O)]·H_2O}_n(2),并对配合物进行X-射线单晶衍射、热重分析、X-射线粉末衍射及固体紫外等表征。结果:配合物1属于单斜晶系,具有含S形链的二维层状结构,配合物2属于三斜晶系,具有含之字形链和直链的二维层状结构,且2种配合物都具有很强的固体紫外吸收。结论:由具有抗菌性的苯并咪唑衍生物与不同金属离子通过自组装合成了具有不同结构的2种新型配合物,为新型抗菌性配合物的设计合成提供了参考。
OBJECTIVE: To study the relationship between the structure and properties of benzimidazoles and to explore the synthetic methods of novel benzimidazoles with antibacterial properties. Methods: Two novel complexes were prepared by the self-assembly of cobalt nitrate, nickel nitrate and 4,4’-bis (benzimidazol-1-yl) biphenyl and isophthalic acid (IPA) The complexes were characterized by X-ray diffraction and X-ray diffraction. The complexes were characterized by X-ray diffraction (XRD), X-ray diffraction (XRD), X-ray diffraction Ray single crystal diffraction, thermogravimetric analysis, X-ray powder diffraction and solid-state UV. Results: Complex 1 belongs to the monoclinic system and has a two-dimensional layered structure with S-shaped chains. The complex 2 belongs to the triclinic system with a two-dimensional layered structure with a zigzag chain and a straight chain The complexes have a strong solid UV absorption. CONCLUSION: Two novel complexes with different structures were synthesized by self-assembly of benzimidazole derivatives with different antibacterial properties and metal ions, which provided a reference for the design and synthesis of novel antibacterial complexes.
