Ruthenium hexafluoride is a dark brown crystalline solid that melts at 54 °C.[1] The solid structure measured at −140 °C is 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.[3]
The RuF6 molecule itself (the form important for the liquid or gas phase) has octahedral molecular geometry, which has point group (Oh). The Ru–F bond length is 1.818 Å.[3]
