Abstract
Differential thermal analysis (DTA) and (19F, 1H) NMR spectroscopy were used to study thermal properties and ion mobility in complex antimony(III) fluorides with amino acids of composition [(CH3)2CH(CH2)CH(NH3)COOH]SbF4 (LeuHSbF4), SbF3[(CH3)2CH(CH2)CH(+NH3)COO−] (SbF3 · Leu), and SbF3[(CH3)2CHCH(+NH3)COO−] (SbF3 · Val). Ionic conductivity in L-leucinium tetrafluoroantimonate(III) was studied using impedance spectroscopy. LeuHSbF4 was found to undergo a diffusion phase transition to a relatively highly conductive state in the range 385–415 K with an attendant loss of thermal stability (softening) of the high-temperature phase.
