Conduction mechanism model, impedance spectroscopic investigation and modulus behavior of the organic–inorganic [(C3H7)4N][SnCl5(H2O)]·2H2O compound

摘要: In this study, the electric properties and modulus formulation of compound [(C3H7)4N][SnCl5(H2O)]·2H2O were studied in 200 Hz to 5 MHz frequency range 343–418 K temperature range. Cole–Cole (Z′′ versus Z′) plots well fitted an equivalent circuit formed by a parallel combination resistance (R), fractal capacitance (CPE) (C). Arrhenius behavior direct current conductivity confirmed transitions observed calorimetric study. The dependence AC on was found satisfy Jonscher's universal power law at different temperatures, σ(ω) = σdc + Aωs. (AC) electrical conduction material is supported two theoretical models that can be attributed non-overlapping small polaron tunneling (NSPT) model phase I correlated barrier hopping (CBH) mechanism phases (II) (III). Moreover, study structure–electronic property relationship implied dominance proton hydrated form (region I). after crystal dehydration (in region II III), assured contribution movements anionic cationic parts. For formalism, extracted activation energies from linear fit ln(fp) as function 1000/T matched with those obtained dc regions (III), which these regions.
