Abstract
The electrical and dielectric properties of the compound C7H12N2[H2PO4]2 ⋅ 1/2H2O were investigated by the complex impedance spectroscopy, over a wide range of frequencies and temperatures, 600 Hz–5 MHz and 303–408 K, respectively. Besides, a detailed analysis of the impedance spectrum suggested that the electrical properties of the material at several temperatures and the electrical equivalent circuit have been proposed to explain the impedance results. Concerning the Nyquist plots, they clearly showed the presence of bulk and grain boundary. As for the imaginary part of modulus at several temperatures, it shows double relaxation peaks, thus suggesting the presence of grains and grain boundary conductions in the sample.
