AB  - Ammonium pertechnetate reacts in mixtures of trifluoromethanesulfonic anhydride and trifluoromethanesulfonic acid under final formation of ammonium pentakis(trifluoromethanesulfonato) oxidotechnetate(V), (NH4)2[TcO(OTf)5]. The reaction proceeds only at exact concentrations and under the exclusion of air and moisture via pertechnetyl trifluoromethanesulfonate, [TcO3(OTf)], and intermediate Tc(VI) species. 99Tc nuclear magnetic resonance (NMR) has been used to study the Tc(VII) compound and electron paramagnetic resonance (EPR), 99Tc NMR and X-ray absorption near-edge structure (XANES) experiments indicate the presence of the reduced technetium species. On moist air, (NH4)2[TcO(OTf)5] slowly hydrolyses under formation of the tetramericoxidotechnetate(V) (NH4)4[{TcO(TcO4)4}4] 10 H2O. Single crystal Xray crystallography was used to determine the solid state structures. Additionally, UV-vis and IR spectra and quantum chemical calculations confirm the identity of the species.
