Notes:
A structural determination of the high-temperature form γ-Sn2F6 has been performed using neutron diffraction. This mixed fluoride exhibits the cubic ordered ReO3-type structure (Fm3m space group) with a = 8.321(4) Å at 497 K. The bond lengths SnII—F and SnIV—F give evidence of the presence of tin(II) in the (a) site and tin(IV) in the (b) site. A cationic ordering has also been found in the intermediate form β-Sn2F6 whose structure is related to the LiSbF6-type.
