Abstrakt:	The results of previously published studies of the ion mobility, phase transitions, and electrophysical properties of tetrafluoroantimonates(iii) with heteroatomic cation sublattices composed of alkali metal and ammonium cations are analyzed, corrected, supplemented, and summarized. The influence of outer-sphere monovalent cations of different nature on the character of ion mobility, phase transitions, and conductivity in crystalline tetrafluoroantimonates(iii) is considered. It was found that phase transitions of most compounds in question are followed by the formation of superionic β-phases with a high conductivity of the order of 10−4–10−2 S cm−1 in the temperature range of 400–500 K.
