Spectroscopic characterization of anionic tris(N,N-dialkyldithiocarbamate) complexes of zinc(II) and cadmium(II)
The infrared and Raman spectra (1500-50 cm-1) of the related complexes Zn(S2CNMe2)2(I), [Bu4N][Zn(S2CNMe2)3] (II), Cd(S2CNMe2)2 (III), [Bu4N][Cd(S2CNMe2)3](IV), Cd(S2CNEt2)2(V) and [Bu4N][Cd(S2CNEt2)3] (VI) have been determined. For complexes with coordination number four, metalsulfur stretching fre...

For complexes with coordination number four, metalsulfur stretching frequencies were assigned at 228 cm-1 for I (ZnS), 180 cm-1 for III (CdS) and 208 cm-1 for V (CdS), whereas for complexes with apparent coordination number six they were assigned at 206 cm-1 for II (ZnS) and in the 150-125 cm-1 range for IV and VI (CdS).
