Abstract

In this paper, a study was carried out and we now report the measurement of impedance spectroscopy for the bis(2-amino- 4-methylpyridinium) tetrachloridozincate (II) compound in the frequency range 209 Hz-5 MHz with the temperature ranging from 308 up to 368 K. The results are represented in impedance plots which have shown semicircle arcs at different temperatures and an electrical equivalent circuit has been proposed to explain the impedance results. Detailed analysis of the impedance spectrum suggests that the electrical properties of the material are strongly temperature dependent. The frequency-dependent conductivity data were fitted in the Jonscher's law: σac(ω) = σdc + Aωn . The conductivity follows the Arrhenius relation. Thus the conduction in the material is probably due to a hopping or a small polar on tunnelling process. It was concluded that the temperature dependence of conductivity was analyzed using the Arrhenius approach. Finally the AC conductivity of [C6H9N2]2ZnCl4 material was studied as a function of temperature (308-368 K) and frequency ranges (209 Hz to 5 MHz), respectively. The AC conductivity has shown a variation with frequency and was found to obey Jonscher’s law: σac = σdc + Aωn at different temperatures. The temperature dependence of the Jonscher’s exponent has revealed that the conduction inside the studied material is insured by the Non-overlapping Small Polaron Tunnelling (NSPT) model.
