The thermal decomposition of transition metal trifluorides MF3 (M = Mn, Fe, Co) was studied by collecting sequences of very-high-energy (89 keV) synchrotron radiation diffraction patterns. The real-time evolution of the crystal lattices was followed as a function of temperature and it was observed that the transition from MF3 to MF2 is generally accompanied by the formation of intermediate short-living phases M2F5. One of them Co2F5 is a phase which had never been observed before.

Abstract
The thermal decomposition of transition metal trifluorides MF3 (M = Mn, Fe, Co) was studied by collecting sequences of very-high-energy (89 keV) synchrotron radiation diffraction patterns. The real-time evolution of the crystal lattices was followed as a function of temperature and it was observed that the transition from MF3 to MF2 is generally accompanied by the formation of intermediate short-living phases M2F5. One of them Co2F5 is a phase which had never been observed before.File in questo prodotto:
