| Abstract: | Cadmium(II) complexes of thiones and thiocyanate, [(>C=S)2Cd(SCN)2], have been prepared and characterized by IR and NMR spectroscopy. An upfield shift in the >C=S resonance of thiones in the 13C NMR and downfield shift in N–H resonance in 1H NMR are consistent with sulfur coordination to cadmium(II). The presence of ν(N–H) of thiones in IR spectra of the complexes indicates the thione forms of the ligands in the solid state; some contribution of the thiolate form was observed in one complex. The appearance of a band around 2100 cm?1 in IR and a resonance around 132 ppm in 13C NMR indicates the binding of thiocyanate to cadmium(II). |
