摘要：

Metal complexes of the type (MLL2)-L-1 [M = Zn, Cd, Hg; L-1 = N-methyl-N-phenyldithiocarbamato and L-2 = N-ethyl-N-phenyldithiocarbamato] have been synthesized and characterized by elemental analyses, FT-IR and NMR spectroscopy. The complexes are formulated as four coordinate species with the dithiocarbamates acting as bidentate chelating ligands. The complexes were thermolysed and used as single-source precursors for the synthesis of HDA-capped MS (M = Zn, Cd, Hg) nanoparticles. The HgS nanoparticles show a narrow size distribution from their TEM images, while the CdS nanoparticles gave crystalline particles with a sharp band absorption edge and a narrow PL band. The ZnS nanoparticles gave crystalline particles with a stacking arrangement. (C) 2010 Elsevier Ltd. All rights reserved.
