Dithiocarbamates 1,2-dithiolene complex

AuCl3(tht) [129], AuX3[S(benzyl)2)2] (X = Cl, Br) [130] and AuC13 (thian-threne). Various dithiocarbamates and dithiolene complexes have been made, some by oxidation of gold(I) complexes (Figure 4.26).

Electrochemical data for gold dithiocarbamate (dtc) complexes are listed in Table 4. Van der Linden and coworkers studied a series of square planar Aum dithiocarbamates, [Au(12)2]+ and mixed 1,2-dithiolene and dithiocarbamate complexes, Au(mnt)(dtc) and Au(tdt)(dtc)10,22. Note that the potentials in these studies were all obtained using a rotating... 

Pt disk electrode10,22. In contrast to the gold 1,2-dithiolene complexes, only one redox couple has been reported for the complexes containing dithiocarbamates. The monocations reduce at less negative potentials than the neutral, mixed complexes. The 1/0 couple for [Au(12)2]+ is irreversible and is fairly insensitive to the substituents bonded to nitrogen. Similarly, in the mixed 1,1- and 1,2-dithiolene complexes, the 0/1 couple is more sensitive to the nature of the 1,2-dithiolene ligand rather than to the substituents on the 1,1-dithiolene ligand.

Substituted dithioformate anions as ligands R C(S)S are usually called dithiocarbamates (R = R2N), alkyl and aryl dithiocarbonates or xanthates (R = RO), alkyl and aryl trithiocar-bonates or thioxanthates (R = RS). Dithioacid anions (R = alkyl, aryl) have been rarely used as ligands of nickel(II) because of their instability. Structural properties of selected nickel(II) complexes with substituted dithioformate, dithiolene and related ligands are shown in Table 90.
