Aerobic oxidation-induced virtual radical coupling of mixed-metal PtRh2 trinuclear complexes accompanied by the formation of a Rh–Rh bond†
Abstract
A mixed-metal PtIIRhI2 trinuclear complex with triply bridging sulfide ligands, generated by the reaction of a Rh(I) nbd complex with a bis(hydrosulfido) Pt(II) complex bearing a bisNHC ligand, is oxidised under aerobic conditions to give a diamagnetic hexanuclear cluster accompanied by the formation of a RhII–RhII bond.
