Platinum pentafluoride

Platinum pentafluoride is the inorganic compound with the empirical formula PtF₅. This red volatile solid has rarely been studied but is of interest as one of the few binary fluorides of platinum, i.e., a compound containing only Pt and F. It is hydrolyzed in water.

The compound was first prepared by Neil Bartlett by fluorination of platinum dichloride above 350 °C (below that temperature, only PtF₄ forms).

Its structure consists of a tetramer, very similar to that of ruthenium pentafluoride. Within the tetramers, each Pt adopts octahedral molecular geometry, with two bridging fluoride ligands.
