Rhodium hexafluoride, also rhodium(VI) fluoride, (RhF6) is the inorganic compound of rhodium and fluorine. A black volatile solid, it is a highly reactive material, and a rare example of a rhodium(VI) compound. It is one of seventeen known binary hexafluoride.
The RhF6 molecule has octahedral molecular geometry. Consistent with its d3 configuration, the six Rh–F bond lengths are equivalent, being 1.824 Å. It crystallises in an orthorhombic space group Pnma with lattice parameters of a = 9.323 Å, b = 8.474 Å, and c = 4.910 Å.
