The trimethylsilanethiolate complexes of the platinum triad metals (dppe)M(SSiMe 3 ) 2 (M = Ni, Pd, Pt) and (COD)Pt(SSiMe 3 ) 2 were prepared by the reaction of NaSSiMe 3 with (dppe)MCl 2 or (COD)PtI 2 . These complexes are water-sensitive. New, sulfido-bridged heterobimetallic complexes L 2 M(μ 3 -S) 2 {Ru(N)Me 2 } 2 resulted from the reactions of (dppe)Pt(SSiMe 3 ) 2, (COD)Pt(SSiMe 3 ) 2, or (dppe)Pd(SSiMe 3 ) 2 with [PPh 4 ][Ru(N)Me 2 Cl 2 ]. The reaction between (dppe)Pt(SSiMe 3 ) 2 and [Os(N)(CH 2 SiMe 3 ) 2 (NCMe) 2 ][BF 4 ] produced (dppe)Pt(μ 3 -S) 2 {Os(N)(CH 2 SiMe 3 ) 2 } 2 . All new compounds have been characterized through spectroscopic techniques and elemental analysis. The molecular structures of (dppe)Pt(μ 3 -S) 2 {Ru(N)Me 2 } 2 and (dppe)Pt(μ 3 -S) 2 {Os(N)(CH 2 SiMe 3 ) 2 } 2 were determined by single-crystal X-ray diffraction.
