F. Burgos et al., A new heterobimetallic Ru,Rh complex with a dianionic pentalene as bridging ligand. Synthesis, crystal structure, and catalytic activity of [Cp*Ru(mu-eta(5),eta(3)-C8H6)Rh(eta(4)-COD)], ORGANOMETAL, 20(7), 2001, pp. 1287-1291
The heterobimetallic complex [Cp*Ru(mu-eta (5),eta (3)-C8H6)Rh(eta (4)-COD)
] (2) is synthesized and characterized spectroscopically and structurally.
The structure of this compound exhibits the two metal centers bonded in an
anti disposition to the pentalenyl ligand. The displacement of the coordina
ted COD by carbon monoxide is studied. The bimetallic complex shows a high
activity and selectivity for the dehydrogenative silylation of styrene.
