Synthesis and spectral studies on Cd(II) dithiocarbamate complexes and their use as precursors for CdS nanoparticles

Bis(N-cyclopropyl-N-4-chlorobenzyldithiocarbamato-S,S')cadmium(II) (1.) and (2,2'-bipyridine) bis(Ncyclopropyl-N-4-chlorobenzyldithiocarbamato-S,S')cadmium(II) (2) have been synthesized and characterized by FT-IR, (FINMR)-F-1 and C-13 NMR analyses. For the complex 2, single crystal X-ray diffraction analysis and computational studies (optimized geometry, HOMO-LUMO and MEP) have been executed employing DFT/B3LYP method with LANL 2DZ basic set. The optimized bond lengths and bond angles agree well with the experimental results. The complexes 1 and 2 have been used as single source precursors for the synthesis of ethyleneglycol capped CdS1 and CdS2 nanoparticles, respectively. CdS1 and CdS2 nano particles have been synthesized by solvothermal method. PXRD, SEM, Elemental colour mapping, EDAX, TEM and UV Vis spectroscopy have been used to characterize the as-prepared CdS nanoparticles. The Xray diffraction pattern confirms both their hexagonal structures. (C) 2017 Elsevier B.V. All rights reserved.
