report the synthesis, characterization, bonding modes, antibacterial and antioxidant studies of half-sandwich ruthenium, rhodium and iridium complexes containing salicylaldehyde based thiosemicarbazone derivatives. All complexes have been prepared by reacting [(arene)MCl2]2 (M = Ru, Rh, Ir) with thiosemicarbazone derivatives (L1, L2, and L3) in 1:2 (M:L) molar ratio respectively. Three mononuclear and
本文中我们报告了含有水杨醛基硫代半脲衍生物的半三明治钌,铑和铱配合物的合成,表征,键合方式,抗菌和抗氧化研究。所有配合物都是通过使[(亚芳基)MCl 2 ] 2(M = Ru,Rh,Ir)与硫半脲衍生物(L1,L2和L3)分别以1:2(M:L)摩尔比反应制备的。已经获得了三个单核和六个双核阳离子配合物,其中氯离子或PF 6或两者(在双核配合物的情况下)都作为它们的抗衡离子。缩氨基硫脲衍生物与金属中心的配合物用于结合模式1 - 3,6和8单晶X射线衍射研究已证实。此外,它们的体外抗菌抗革兰氏阳性活性金黄色葡萄球菌和革兰氏阴性大肠杆菌,肺炎克雷伯氏菌菌株已经过测试。还已经评估了这些复合物的最小抑菌浓度(MIC)和最小杀菌浓度(MBC)。这些化合物的抗氧化活性也已经过测试。配合物1和4的DNA结合研究因其良好的荧光强度而得到评估,并在补充信息中介绍。
