Experimental and theoretical study of AC electrical conduction mechanisms of Bis (4-acetylanilinium) tetrachloridozincate

The Bis (4-acetylanilinium) tetrachloridozincate [C8H10NO]2[ZnCl4] compound was obtained by slow evaporation at room temperature and characterized by XRD. It is crystallized in an orthorhombic system (Cmca space group). The material was characterized by impedance spectroscopy technique measured in the 209 Hz–5 MHz frequency range from 423 to 498 K. Besides, the Cole–Cole (Zʺ versus Z′) plots were well fitted to an equivalent circuit built up by a parallel combination of resistance (R), fractal capacitance (CPE) and capacitance (C). Furthermore, the AC conductivity was investigated as a function of temperature and frequency in the same range. The experimental results indicated that AC conductivity (σac) was proportional to AωS1+BωS2AωS1+BωS2(0
