prepared β‐MnF4 photochemically according to the literature and obtained a phase‐pure powder as evidenced by X‐ray diffraction at room temperature. The lattice parameters are a = 19.566(3), c = 12.984(2) Å, V = 4304(1) Å3. IR and Raman spectra recorded on the powder show that β‐MnF4 has also been obtained free of moisture, HF, and O2+ containing compounds, however MnF3 is likely present as a magnetic impurity

system KrF2—MnF2—HF two new adducts, 2KrF2·MnF4 and KrF2·MnF4 have been synthesized. The 2 : 1 adduct decomposes in a dynamic vacuum at −45°C yielding KrF2 and the 1 : 1 adduct, which is stable in a dynamic vacuum up to −25°C. KrF2·MnF4 decomposes further at room temperature to krypton, fluorine, krypton difluoride and manganese tetrafluoride. This reaction is a useful synthetic route for the preparation

The mechanism for the chemical synthesis of F2 has been elucidated by experimental and electronic structure theory methods. The elimination of F2 from MnF4 requires a large excess of SbF5 occurring in the last reaction step by addition of SbF5 to the intermediate [SbF6][MnF2][Sb2F11]− anion producing F2 and crystalline Mn[Sb2F11]2.
