Six complexes of Zn(II), Cd(II) and Hg(II) with sulphur containing Schiff base ligand, 1,4‐bis((1 H ‐pyrrol‐2‐yl)methylene)thiosemicarbazide in 1:1 and 1:2 ratio has been synthesized. Complexes were characterized by molar conductance measurement, elemental analyses, FT‐IR, 1 H‐NMR, and FAB/ESI‐Mass. The complexes were used as a single source precursor for the synthesis of ZnS/CdS/HgS nanoparticles by their thermal 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 base, complexes and nanoparticles were tested for antibacterial activity and MIC values against E. coli . The complexes were found more potent than the corresponding Schiff bases and nanoparticles.
