Ion mobility and phase transitions in heptafluorodiantimonates(III) Cs (1−x) (NH 4 ) x Sb 2 F 7 and K 0.4 Rb 0.6 Sb 2 F 7 according to NMR and DSC data

Synthesis, crystal structure, and properties of pentadecafluorotetraantimonate(III) CsRb2Sb4F15

“…The structure and physical-chemical properties of many complex penta-, tetra-, and heptafluoroantimonates(III) as with homogeneous as with mixed monovalent cations have been investigated rather thoroughly [1][2][3][4][5][6][7][8][9][10][11]. Many compounds in these series are characterized by the presence of phase transitions with formation of modifications, in which the diffusion of fluorine (ammonium) ions causing high ionic conductivity is a dominating type of ionic motions [3,4,[10][11][12]. The compounds belonging to the group of pentadecafluoroantimonates(III), in which the ratio F:Sb = 3.75, have been studied insufficiently.…”
