Tc(VII) oxyfluorides; Preparation and study by 99Tc NMR, raman spectroscopy and x-ray crystallography

Although TcO3F can be prepared by solvolysis of TcO4− in anhydrous HF and ReO2F3 and ReOF5 have been known for some time, the preparations of the higher oxyfluorides of Tc(VII) have not been reported.The noble-gas fluorides KrF2 and XeF6 are potent oxidative fluorinating agents and provide a ready means to the syntheses of the higher oxyfluorides of Tc(VII). Thus, XeF6 and KrF2 oxidative fluorinations of TcO3F in HF media lead to the stepwise …
