Zn(II), Cd(II), and Hg(II) dithiocarbamate complexes were synthesize and characterized by elemental analysis, thermogravimetric analysis, UV-Vis, FTIR, and H-1-and C-13-NMR spectroscopy. Single-crystal X-ray crystallography revealed that the Zn complex has a centrosymmetric dimeric structure while the Hg complex crystallizes with two monomeric molecules of the mercury complex and two molecules of toluene solvent in the asymmetric unit. The compounds were used as single molecule precursors to synthesize HDA capped metal sulfides nanoparticles with average crystallite size ranging from 7 to 22 nm. The optical properties of the nanoparticles showed evidence of quantum confinement.
