The [N(CH3)4][N(C2H5)4]ZnCl4 compound was prepared and characterized by electrical technique. The temperature dependence of the dielectric permittivity shows that this compound is ferroelectric below T = 268 K. The two semi-circles observed in the complex impedance identify the presence of the grain interior and grain boundary contributions to the electrical response in the material. The equivalent circuit is modeled by a combination series of two parallel RP-CPE circuits. The frequency dependent conductivity is interpreted in term of Jonscher's law. The modulus plots can be characterized by the empirical Kohlrausch-Williams-Watts (K.W.W.) function: 蠒(t) = exp [(鈭抰/蟿)尾]. The temperature dependence of the alternative current conductivity (蟽p), direct current conductivity (蟽dc) and the relaxation frequency (fp) confirm the presence of the ferroelectric-paraelectric phase transition.
