The crystal structure determination of Rh2(dippe)2(/u,-H)(ju,-T T -CH=CH2) (6a) reveals a disordered vinyl group and an asymmetrically bridging hydride ligand [Rh(l)-H distance 1.84(4) A and Rh(2)-H dis- 

Selected X-Ray data for o-.tt-Bridced VrNVL Moieties in Bimetallic Complexes 

It has been postulated that the formation of a /r-Tj iTj -vinyl ligand in binuclear intermediates involves the activation of a coordinated olefin by one metal center followed by an intramolecular oxidative addition of a
