Ruthenium hexafluoride, also ruthenium(VI) fluoride (RuF 6), is a compound of ruthenium and fluorine and one of the seventeen known binary hexafluorides.
Synthesis [ edit ]
Ruthenium hexafluoride is made by a direct reaction of ruthenium metal in a gas stream of
fluorine and argon at 400–450 °C. The yields of this reaction are less than 10%. [2 ]

Description [ edit ]
Ruthenium hexafluoride is a dark brown crystalline solid that melts at 54 °C.
The solid structure measured at −140 °C is [1 ] orthorhombic space group Pnma. Lattice parameters are a = 9.313 Å, b = 8.484 Å, and c = 4.910 Å. There are four formula units (in this case, discrete molecules) per unit cell, giving a density of 3.68 g·cm −3. [2 ]
6 molecule itself (the form important for the liquid or gas phase) has octahedral molecular geometry, which has point group ( ). The Ru–F O h bond length is 1.818 Å. [2 ]
