Complexes 1–9 were prepared by the reaction of [(arene)MCl2]2 (arene = p-cymene, Cp*; M = Ru, Rh and Ir) with thiourea derivative ligands L1, L2 and L3. These complexes have been isolated as cationic bidentate (N, S), neutral bidentate (N, S) as well as neutral mono-dentate (S) complexes. Anti-bacterial activity studies were carried out for these complexes as well as the ligands against Gram-positive
配合物1–9是通过[[arene)MCl 2 ] 2(芳烃= 对甲基异丙基苯,Cp *; M = Ru,Rh和Ir)与硫脲衍生物配体L1,L2和L3反应制得的。这些配合物已被分离为阳离子双齿(N,S),中性双齿(N,S)以及中性单齿(S)配合物。对这些复合物以及针对革兰氏阳性菌(金黄色葡萄球菌)和革兰氏阴性菌(大肠杆菌;肺炎克雷伯菌)的配体进行了抗菌活性研究,其中所有复合物(复合物2和3除外)6)以及配体(L3除外)均表现出抗菌活性。除了生物学研究,还进行了使用银纳米粒子的比色传感研究,其中配体L1和L3表现出团聚作用。
