Treatment of a methanolic solution of metal acetate with bis(1-methylimidazolyl)diselenide, (MeImSe)2, yields complexes of composition M(OAc)2{(MeImSe)2} (M = Zn, Cd, or Hg) whereas reactions of MX2(Me2NCH2CH2NMe2) (X = Cl or OAc) with sodium 1-methylimidazole-2-selenolate gave selenolate complexes of the general formula M(MeImSe)2 (M = Zn or Cd). The complexes were characterized by elemental analysis, IR, UV–vis, NMR (1H, 13C, and 77Se) data. The crystal structure of Cd(OAc)2{(MeImSe)2} was established by single-crystal X-ray diffraction. The cadmium atom adopts a distorted octahedral configuration defined by asymmetrically chelated acetate groups and chelating diselenide ligand. Thermal behavior of adducts was studied by thermogravimetric analysis. Pyrolysis in hexadecylamine/tri-n-octylphosphine oxide gave MSe quantum dots, which were characterized by UV–vis, photoluminescence, XRD, EDAX, SAED, and TEM.
