Abstract
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
13
C NMR and downfield shift in N-H resonance in
1
H 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
13
C NMR indicates the binding of thiocyanate to cadmium(II).
