Abstract
Internal mobility in TlSb4F13 (I) and TlSb3F10 (II) was studied by 19F NMR spectroscopy in the temperature range 210-450 K. Types of ionic motion in the fluoride subsystem were determined. Phase transitions resulting in modifications with high ionic (superionic) conductivity above 420 K were established for both compounds (385-425 K). Using impedance spectroscopy, we studied the electrophysical properties of I and II in the temperature range 290-425 K ( and S/cm for I and II, respectively; K).
