thiourea derivatives 1-phenyl-3-(pyridin-2-yl)thiourea (L1), 1-phenyl-3-(pyrazin-2-yl)thiourea (L2), 1-(4-methylpyridin-2-yl)-3-phenylthiourea (L3) and 1-benzyl-3-(pyridin-2-yl)thiourea (L4). The complexes have been fully characterized by IR, UV–Vis, NMR and ESI-MS spectral methods. The molecular structures of complexes 1 and 3 were established by single-crystal X-ray diffraction studies. Furthermore
通过[ CpRu ( PPh 3 ) 2 Cl ]或[ _ _ (Ind)Ru(PPh 3 ) 2 Cl] (Cp=η 5 -C 5 H 5 , Ind=η 5 -C 9 H 7 )与各自的吡啶基/嘧啶基硫脲衍生物1-苯基-3-(吡啶-2-基)硫脲(L1)、1-苯基-3-(吡嗪-2-基)硫脲(L2)、1-(4-甲基吡啶-2-基)-3-苯基硫脲(L3)和1-苄基-3- (吡啶-2-基)硫脲 (L4 )。配合物已通过 IR、UV-Vis、NMR 和 ESI-MS 光谱方法进行了充分表征。通过单晶 X 射线衍射研究确定了配合物1和3的分子结构。此外,针对自由基清除活性和致病菌如金黄色葡萄球菌、大肠杆菌和肺炎克雷伯菌,筛选了配合物 ( 1-8)和配体。
