Ruthenium pentafluoride

Ruthenium pentafluoride is the inorganic compound with the empirical formula RuF₅. This green volatile solid has rarely been studied but is of interest as a binary fluoride of ruthenium, i.e. a compound containing only Ru and F. It is sensitive toward hydrolysis. Its structure consists of Ru₄F₂₀ tetramers, as seen in the isostructural platinum pentafluoride. Within the tetramers, each Ru adopts octahedral molecular geometry, with two bridging fluoride ligands.
