Gold-stibine complexes

Reaction of Au(tht)Cl with SbMes3 resulted, regardless of the molar ratio used, in the isolation of the neutral complex Au(SbMes3)Cl 118, which also contains a linear Sb-Au-Cl system (Figure 4.32d), with the shortest Au-Sb bond [2.5100(2) A] found so far in gold-stibine complexes. For none of these complexes was further association of the molecules observed in the solid state. 

Linear Gold(I) Complexes with Monodentate Phosphine, Arsine or Stibine Ligands 882... 

The number of gold complexes containing tertiary phosphines, arsines, or stibines as ligands is large because of the wide use of the fragment AuL+, mainly with L = PPh3, in the synthesis of... 

These complexes are stable and easily prepared, and so are very commonly used in gold(I) chemistry. The usual synthetic method involves reaction of [AuCU]- with the tertiary phosphine, arsine or stibine (equation 43 Y = P, As or Sb, R = alkyl or aryl). The phosphine acts as both reducing agent and ligand in these reactions, and the mechanism has been studied in detail.328...
