Dielectric dispersion studies in (C3N2H5)2SbF5

The dielectric properties of (C3N2H5)2SbF5 were studied in the frequency range of 40 Hz−5 MHz and temperature range 343−190 K. There are two dispersion ranges. The first one observed in the range of 10 kHz−5 MHz and temperature range 300−220 K is connected with dipolar relaxation process. The dispersion observed on the crystal plates normal to the a and c crystallographic axes is quite similar. Activation energies connected with dipolar relaxation for both mentioned directions Ed are equal to 0.335 ± 0.020 eV. The second dispersion observed in the frequency range of 40 Hz–10 kHz and temperature interval of 343−250 K is supposed to be connected with ionic conductivity. Activation energies for the crystal plates normal to the a and c crystallographic axes are close and equal to Ec = 0.50 ± 0.01 eV and Ec = 0.45 ± 0.01 eV, respectively. The dispersion observed on the crystal plate normal to the b axis in the frequency range of 40 H–10 kHz and temperature range of 300−343 K is connected with supposed ionic conductivity with an activation energy Ec = 0.75 ± 0.02 eV.
