Pt[SiH(C6H4F-4)(2)}(2)(PMe3)(2) reacts with Rh (I) complexes to afford new Rh-Pt heterobimetallic complexes with bridging hydrido and diarylsilyl ligands. These complexes were characterized by X-ray crystallography. The NMR spectra exhibit dynamic behavior of hydrogen atoms and three PMe3 ligands bonded to Rh center in solution.
