Nine lead bis(dithiocarbamate) complexes based on benzyl and furfuryl groups have been prepared. The complexes were characterized using IR and NMR spectroscopy. All the complexes showed the expected signals in (1)H and (13)C NMR spectra associated with the dithiocarbamate ligands. IR and (13)C NMR spectral studies indicate that the S(2)CN double bond character increases with increase in length of alkyl chain bonded to nitrogen atom. Bis(N-benzyl-N-(2-phenylethyl)dithiocarbamato-S,S')lead(II) (3) and bis(N-furfuryl-N-(2-phenylethyl)dithiocarbamato-S,S')lead(II) (4) have been used as single source precursors for the synthesis of ethylenediamine capped PbS nanoparticles. Powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), FTIR, UV-vis and fluorescence spectroscopy have been used to characterize the as-prepared lead sulfide nanoparticles. The PXRD measurements suggest that PbS nanoparticles are single phase with face-centered-cubic structure.
