| fussnote | The ionic conductivity of members of K"3"-"xM"xZrF"7 (M = NH"4, Tl and 0 =〈 x =〈 3) solid solutions was investigated using complex impedance spectroscopy. Transient NMR measurements were carried out on ^1^9F, ^1H and ^2^0^5Tl in order to specify the mobile species. The structure of KTl"2ZrF"7 has been refined from single crystal diffraction data. Correlations between all these experiments results allow to conclude that a long-range motion of the monovalent cations enhanced by the rotational/reorientational motion of the (ZrF"7)^3^- complex anions is responsible for the ionic conductivity of these phases. Comparison of the ionic conductivities of Tl, NH"4 and K compounds as well as that of some compositions among their solid solutions supports the conclusion that the higher performances of the pure thallium compound can be related to the high polarisability of this ion. |
