Stepwise ligand exchange from 1 leads to the unique dinuclear complex 3 , in which a trialkylphosphane is linked in a bridging position to two transition metal centers. In the isolated intermediate [ClRh( μ ‐PMe 3 )( μ ‐CPh 2 ) 2 Rh(acac)] ( 2 ) the phosphane behaves as a semibridging unit, as confirmed by an X‐ray crystal structure analysis. acac=acetylacetonate.
