Seven new coordination compounds of 1,3-bis(benzo-1,2,3-triazol-1-yl)propane (L3), 1,4-bis(benzo-1,2,3-triazol-1-yl)butane (L4) and 1,6-bis(benzo-1,2,3-triazol-1-yl)hexane (L6) with cadmium(II) or silver(I) nitrates were prepared, characterized by single crystal X-ray diffraction, IR spectroscopy, thermogravimetric analysis and luminescence studies. It was found that depending on the solvent used, cadmium(II)
摘要通过1,2,3-苯并三唑与相应的二溴代烷烃反应制得了一系列双(苯并-1,2,3-三唑基)烷烃。这些柔性多齿配体的单个异构体通过选择性氯化铜(II)配合物形成而分离。1,3-双(苯并1,2,3-三唑-1-基)丙烷(L3),1,4-双(苯并1,2,3-三唑-1-基)的七个新配位化合物制备了丁烷(L4)和1,6-双(苯并-1,2,3-三唑-1-基)己烷(L6)与镉(II)或硝酸银(I),并通过单晶X射线表征衍射,红外光谱,热重分析和发光研究。发现根据所使用的溶剂,硝酸镉(II)与丙酮中的配体L3和乙腈中的1D配位聚合物形成离散的双核络合物。具有较长接头的配体L4和L6在丙酮和乙腈中均与硝酸银形成了二维配位聚合物。具有L6的银配位聚合物对白葡萄球菌,铜绿假单胞菌和肺炎克雷伯菌具有杀菌作用。
