Most bimetallic complexes have a common structural motif in which each metal center has four bidentateligandsbridging the two metals. Double deckerligandsdeveloped in our research groupmetallatewith three bidentateligandstied to an amine base and have two planes of heteroatomsto chelateto the bimetallic unit. This structural arrangement caps off one metal center, isolating the reactivity of the complex to a single metal site. In this way the supporting role of the second center can be assessed. One such ligand, a tris-phenyl amide, has been used to make two novel dirhodiumcomplexes similar to catalysts used for carbenetransfers.
