Binuclear gold compounds, [Au(R₂PC(S) NR′)]₂, were characterized from the reactions of HAuCl₄ or Ph₃PAuCl with R₂PC(S)N(H)R′. The complexes feature bidentate bridging ligands that link two gold centres leading to eight-membered metallacycles and linear S-Au-P coordination geometries. In the case of [Au(Ph₂PC(S)NPh)]₂, crystal structure analysis shows the presence of two conformations in the one lattice, i.e. an extended chair and a twisted conformation.
