Abstract：A new Schiff base containing sulphur, 1-phenyl-3-methyl-4-(α-furoyl)pyrazolone-5-thiosemicarbazone (HL) and its Zn(Ⅱ), Cd(Ⅱ) and Co(Ⅱ) complexes have been synthesized. On the basis of elemental analysis and molar conductance, the general formulae of the complexes, [ZnL2]·1.5H2O, [CdL2]·C2H5OH and [CoL2]·H2O, were given. They were characterized by IR, UV-Visible, 1H NMR, 13C NMR and magnetic moments. The results show that the metal ions exhibit coordination of six in the complexes. The antibacterial experiments indicate that they have high antibacterial activities against S. aureus, B. subtilis, E. coli, E. carotovora, and C. flaccumfaciens.
