Abstract 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.
