derivative ligands (L1, L2 and L3) yielded a series of mononuclear ruthenium, rhodium and iridium complexes and their corresponding dinuclear analogues. All these complexes (1-9) were characterized by analytical and spectroscopic techniques. Single-crystal X-ray diffraction studies determined the molecular structures of complexes 1, 5, 7-9. The compounds were screened for their in vitro antibacterial activity
卤化物桥接金属前体 [(芳烃) MCl 2 ] 2 (芳烃 = 对伞花烃,Cp*;M = Ru、Rh 和 Ir) 与缩氨基硫脲衍生物配体 ( L1、L2和L3 ) 反应生成一系列单核钌、铑和铱配合物及其相应的双核类似物。所有这些复合物 ( 1-9 ) 都通过分析和光谱技术进行了表征。单晶 X 射线衍射研究确定了配合物 1、5、7-9 的分子结构。筛选化合物对革兰氏阳性金黄色葡萄球菌(MTCC 3160、MMSA、ESKAPE)和苏云金芽孢杆菌的体外抗菌活性(MTCC 8995) 和革兰氏阴性大肠杆菌(MTCC 1687) 和铜绿假单胞菌(MTCC 1688, ESKAPE) 菌株,它们表现出显着的抗菌作用。此外,还使用 DPPH 自由基清除试验研究了这些化合物的抗氧化活性,其中大多数化合物显示出显着的抗氧化活性。此外,通过紫外-可见吸收光谱研究,配体L3与生物分子如鲑鱼鱼 DNA (SM-DNA)
