Synthesis of (dppe)Pt(mu(3)-S)(2){Ru(N)Me-2}(2), (dppe)Pt(mu(3)-S)(2){Os(N)(CH2SiMe3)(2)}(2), and related heterometallic complexes

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 rea ction of NaSSiMe3 with (dppe)-MCl2 or (COD)PtI2. These complexes are water- sensitive. New, sulfido-bridged heterobimetallic complexes L2M(mu (3)-S)(2) {Ru(N)Me-2}(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] produce d (dppe)Pt(mu (3)-S)(2){Os(N)-(CH2SiMe3)(2)}(2). All new compounds have bee n characterized through spectroscopic techniques and elemental analysis. Th e molecular structures of (dppe)Pt(mu (3)-S)(2){Ru(N)Me-2}(2) and (dppe)Pt( mu (3)-S)(2){Os(N)(CH2SiMe3)(2)}(2) were determined by single-crystal X-ray diffraction.
