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.
