Chemistry of Aminopropylchalcogenolate Complexes of Zinc, Cadmium, Mercury and Their Nanoparticles

Abstract

The chemistry of aminopropylchalcogenolate complexes of zinc, cadmium, mercury and their nanoparticles are described. A variety of Zinc (II), Cadmium (II), and mercury (II) complexes containing 3-aminopropylchalcogenolate ligand has been prepared by in situ reduction of bis(3-aminopropyl)dichalcogenide to 3-aminopropylsodiumchalcogenolate followed by reaction with metal halides. Nanoparticles have been prepared by solvo-thermal decomposition of these complexes in quinolene solvent at 200°C. The complexes have been characterized by elemental analyses and IR. The prepared nanoparticles have been characterized by XRD, UV-Vis, PL, SEM, and TEM. The TEM images show that the nanoparticles are in the range of 10–20 nm.
