The trimethylsilanethiolate complexes of the platinum triad metals (dppe)M(SSiMe3)2 (M = Ni, Pd, Pt) and (COD)Pt(SSiMe3)2 were prepared by the reaction of NaSSiMe3 with (dppe)MCl2 or (COD)PtI2. These complexes are water-sensitive. New, sulfido-bridged heterobimetallic complexes L2M(μ3-S)2{Ru(N)Me2}2 resulted from the reactions of (dppe)Pt(SSiMe3)2, (COD)Pt(SSiMe3)2, or (dppe)Pd(SSiMe3)2 with [PPh4][Ru(N)Me2Cl2]. The reaction between (dppe)Pt(SSiMe3)2 and [Os(N)(CH2SiMe3)2(NCMe)2][BF4] produced (dppe)Pt(μ3-S)2{Os(N)(CH2SiMe3)2}2. All new compounds have been characterized through spectroscopic techniques and elemental analysis. The molecular structures of (dppe)Pt(μ3-S)2{Ru(N)Me2}2 and (dppe)Pt(μ3-S)2{Os(N)(CH2SiMe3)2}2 were determined by single-crystal X-ray diffraction.
