      abstract     = {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.},
