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
