摘要：

Cadmium(II) complexes of thiones and thiocyanate, [(>C = S)(2)Cd(SCN)(2)], have been prepared and characterized by IR and NMR spectroscopy. An upfield shift in the >C = S resonance of thiones in the C-13 NMR and downfield shift in N-H resonance in H-1 NMR are consistent with sulfur coordination to cadmium(II). The presence of nu(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 C-13 NMR indicates the binding of thiocyanate to cadmium(II).
