  • Abstract

    Twelve complexes of Zn(II), Cd(II) and Hg(II) with two sulphur containing Schiff base ligands, 1-benzylidenethiosemicarbazide (1-BTC) and 1,4-dibenzylidenethiosemicarbazide (1,4-DBTC) in 1:1 and 1:2 ratio have been synthesized. Complexes were characterized by molar conductance, elemental analyses, FT-IR, 1H NMR and FAB/ESI-mass. The complexes were used as a single source precursor for the synthesis of ZnS/CdS/HgS nanoparticles by their pyrolytic decomposition in the presence of different surfactants. The precursor : surfactant ratio and temperature plays important role in determining the size of the nanoparticles. The size and morphology of nanoparticles has been ascertained by UV-Vis spectroscopy, XRD measurements and transmission electron microscopy (TEM). Schiff bases, complexes and nanoparticles were screened for antibacterial activity and MIC values against E. coli. The complexes were found more potent than the corresponding Schiff bases and nanoparticles
