A SiPt bond is the result of the migration of a silyl ligand from one metal center to another. This rearrangement was proven for the first time for 1 a and 1 b and is highly dependent on the ligands. This is illustrated by the observations that 1 b could be isolated as a solid and in solution rearranges much slower than 1 a and that analogous complexes like 1 c do not isomerize.
