their anion relatives in anhydrous hydrogen fluoride solution by strong fluoride ion acceptors such as AsF5 provides a general approach to the synthesis of polymericbinary fluorides and is particularly advantageous in the synthesis of highest-oxidation-state transition metal polymeric fluorides.

Mass spectrometry was used to identify and to thermochemically characterize the gaseous fluorides RuF4 , RuF3 , RuF2 , and RuF generated by fluorination of Ru powder in a platinum effusion cell. Reaction enthalpies and bond dissociation energies were derived from equilibrium measurements involving these species, yielding the following results in kJ mol−1 : D°(F3 Ru–F)=361; D°(F2 Ru–F)=339; D°(FRu–F)=464; and D°(Ru–F)=402. The results show that the +4 oxidation state dominates the high temperature chemistry of the Ru–F system. Results are compared with the properties of the neighboring Mo–F system.
