direct synthesis of cds nanoparticles via simple one-pot calcination of new two-dimensional cd(ii) coordination polymer

Assembly of quinoxaline with cd(ii) in the presence of scn− anion produces a new coordination polymer [cd(quinoxaline)(scn)2(ch3cn)] n [cd(quinoxaline)2(scn)2] n (1) and is characterized by ir, 1h nmr and 13c nmr spectroscopy. the single-crystal x-ray data of compound 1 show that this coordination polymer grows in two-dimensional supramolecular structure. in this polymer, the organic ligand chelate through its one nitrogen atom to cadmium(ii) atom and thiocyanate anion acts as a bridge to two cadmium(ii) atom in the chains. also, nanoscale of cds has been synthesized by calcination at 400, 500 and 600 °c under air atmosphere and characterized by scanning electron microscopy, x-ray powder diffraction and energy-dispersive x-ray. the thermal stability of compound 1 was studied by thermal gravimetric and differential thermal analyses.
