摘要:
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 lending 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.
