Controlled Synthesis of Early-Late Zr-Ir-Rh Heterotrimetallic Compounds by Metal Exchange Reactions.
Sulfido ligands meet the coordination and electronic requirements for stabilizing compounds containing divergent metal centers in close proximity, as shown by the controlled syntheses of early-late bimetallic (ZrIr(2) and ZrIr) and trimetallic complexes (ZrIrRh). The slow rotation of one 1,3-di-tert-butylcyclopentadienyl (Cp(tt)) ring in 1 (structure shown) allows the observation of two rotamers at room temperature. cod=1,5-cyclooctadiene. [Cp(tt)(2)Zr(µ(3)-S)(2){Ir(CO)(2)}{Rh(cod)}] 1
