[H2amtaz]+ iron fluorides: Synthesis, crystal structures, magnetic and Mössbauer studies

57Fe Mössbauer spectra of Fe3F10(H2amtaz)2 at 77 K and 300 K. The results are consistent with the presence of both +II and +III valences for iron cations; their proportion 0.65(1)/0.35(1) at 77 K is in fair agreement with the ratio deduced from the crystallographic determination.
