Description
The fluorine motion in MSn2F5 compounds was investigated using NMR measurements of spin lattice relaxation times T1 at various temperatures and frequencies. In the 250 K - 420 K temperature range the T1 behaviour is quite similar for M = K, Rb, Tl, NH4. Activation energies and correlation times are deduced from these data. NMR and conductivity results show that fluorine ions exhibit a high mobility. Taking into account crystallographic data it is shown that electrical conductivity is strongly dependent on the cation polarisability and is due to the motion of fluorine ions inside Sn-F layers on partially occupied sites.
