Abstract
A new compound of formula (C8H12N)3SnCl6·Cl is obtained at room temperature by slow evaporation of aqueous solution. Structural analysis indicates that this compound crystallizes in the monoclinic system with P21/C space group. The N–ZH⋯Cl hydrogen bonds between (C8H12N)+ cations, Cl− anions and [SnCl6]2− dianions contribute to the cohesion and the stability of the atomic arrangement. One phase transition is detected by differential thermal analysis at 330K. Dielectric studies of this compound were studied in the frequency from 100Hz to 1MHz and a temperature ranging between 290K and 380K. The analysis of Nyquist plots are well fitted to an equivalent circuit consisting of series of combination of grains and grain boundary elements. The AC conductivity was studied using the following equation:σAC(ω)=σs1+τ2ω2+σ∞τ2ω21+τ2ω2+BωS. The temperature dependence of the power law exponent s and a.c conductivity σac is reasonably interpreted by Correlated Barrier Hopping and Small Polaron Tunneling models.
