The new hybrid compound “Bis-2-amino-4-picolinium tetrachloro-mercurate-zincate ((C6H9N2)2(Hg0.12Zn0.88)Cl4)” was prepared by hydrothermal method using HCl as solvent and characterized by XRD, NMR-MAS 13C and electrical impedance spectroscopy. The XRD reveals that the compound was crystallized in the triclinic system, centrosymetric space group P1¯ and the lattice parameters a=7.578(1)Å, b=8.559(1)Å, c=15.418(2)Å, α=84.443(1)°, β=89.506(1)°, γ=68.615(1)° and Z=2.The AC electrical conductivity and the dielectric relaxation properties were measured in the frequency range of 209 Hz–5 MHz at different temperature. The alternating current (AC) conductivity of the investigated compound obeys the Jonscher law: σ(ω)=σdc+Aωn. Furthermore, the temperature dependence of the Jonscher's exponent shows that the conduction inside the studied material is insured by the model: overlapping-large polaron tunneling (OLPT) model.
