Triazolediylidenes: A Versatile Class of Ligands for the Preparation of Discrete Molecules of Homo‐ and Hetero‐Binuclear Complexes for Improved Catalytic Applications

Double trouble: A series of complexes of rhodium and iridium has been obtained with a triazolediylidene ligand, which behaves as an extraordinarily versatile Janus-type ligand to form dinuclear complexes. The dinuclear complexes showed improved catalytic properties over their mononuclear counterparts. The picture shows a diiridium complex of 1,2,4-trimethyltriazole-3,5-diylidene (Ir gray, C white, N blue, O red, Cl green).
