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.
