Abstract

New syntheses of RuF₆ and RhF₆ are reported involving fluorination of the corresponding pentafluorides at 220 °C and 30 atm. Infra-red spectra for RuF₆ and RhF₆ isolated in nitrogen and argon matrices at 12 K have been recorded and assigned. The u.v.–visible spectra in nitrogen matrices are complex containing both fluorine-to-metal charge-transfer and d–d transitions. Assignments for the main features are proposed.
