A new synthetic approach has provided RuF[sub 4] as a deep pink polycrystalline solid from the interaction of AsF[sub 5] with RuF[sub 6][sup 2[minus]] in anhydrous hydrogen fluoride solution. The structure has been determined from a combination of X-ray synchrotron and neutron powder diffraction data. The unit cell, refined from the neutron data, is monoclinic. Each Ru atom has six near-neighbor F ligands on an octahedral framework, four in the same plane, each shared with another Ru atom, to form a puckered-sheet array. The fluorine-bridge bonding is very similar to that which occurs in RuF[sub 3] and in the tetrameric molecule (RuF[sub 5])[sub 4]. The structure of RuF[sub 3] has been confirmed from X-ray powder data on samples prepared by pyrohydrolysis of SF[sub 3]RuF[sub 6]. The structure of RuF[sub 5] has been redetermined for this comparison and found to have a monoclinic unit cell.
