Preparation of high-oxidation-state platinum group metal fluorides in flow systems. Synthesis of the metal hexafluorides, MF6 (M  Ru, Rh, Os, Ir, Pt), ruthenium pentafluoride tetramer, (RuF5)4, and the novel trimer, (RuF5)3

Abstract The fluorination of platinum metals under anhydrous conditions in a flow system yields the volatile metal hexafluorides (M  Ru, Rh, Os, Ir, Pt) in high yield. The flow fluorination of ruthenium also affords green {RuF5}4 and bright red {RuF5}3. In the case of palladium, no volatile products were observed, the only product of the reaction being PdII[PdIVF6].
