A new series of PdII complexes derived from thiosemicarbazone has been synthesized. The synthesized PdII complexes have been characterized on the basis of elemental analyses, FT-IR, ¹H- and ¹³C-NMR, UV/VIS, and thermal studies. A square-planar geometry has been assigned around PdII ions on the basis of results obtained from UV/VIS studies. The thiosemicarbazone ligand and its PdII complexes have been screened against Gram-positive (Bacillus subtilis and Staphylococcus aureus) and Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacteria in vitro as growth-inhibiting agents, and the results revealed significant antibacterial activities.
合成了一系列新型的钯(II)配合物，这些配合物是由缩硫酮衍生而来的。根据元素分析、FT-IR、1H-NMR 和 13C-NMR、UV/VIS 和热研究对合成的钯(II)配合物进行了表征。根据 UV/VIS 研究的结果，确定钯(II)离子周围的几何形状为正方形平面。体外筛选了缩硫酮配体及其钯(II)配合物对革兰氏阳性（枯草芽孢杆菌和金黄色葡萄球菌）和革兰氏阴性（大肠杆菌和铜绿假单胞菌）细菌的抑制生长作用，结果表明它们具有显著的抗菌活性。
