Abstract
The (C7H10NO)(2)SnBr6 center dot 2H(2)O compound is characterized by using the X-ray powder analysis, thermogravimetric analyses, differential scanning calorimetry (DSC) and complex impedance spectroscopic data. This compound exhibits a phase transition at 300 K which is characterized by differential scanning calorimetry, AC conductivity and dielectric measurements. The measurements of impedance spectroscopic are carried out in the frequency range from 100 Hz to 1 MHz with temperatures varying between 275 and 330 K. The impedance measurements indicate that the electrical properties are strongly temperature dependent. Nyquist plots (-Z'' versus Z') show that the conductivity behavior is accurately represented by an Rp//CPE equivalent electrical circuit model. Besides, the frequency dependence of conductivity follows Jonscher's dynamical law with the relation: . The relaxation mechanism can be observed in the complex modulus analysis M-* and the complex polarizability alpha(*).
