Platinum hexafluoride is the
chemical compound with the
formula PtF6. It is a dark-red volatile solid that forms a red gas. The compound is a unique example of platinum in the +6 oxidation state. With only four d-electrons, it is
paramagnetic with a
triplet ground state. PtF
6 is a strong oxidant and a strong fluorinating agent. PtF
6 is
octahedral in both the solid state and in the gaseous state. The Pt-F bond lengths are 185
picometers.
