摘　　要：The dielectric properties of tetramethylammonium monoiodide and pentaiodide were investigated in broad temperature range(-150℃till+50℃).It was demonstrated that the structural organization of the polyiodide chain containing I...I charge-assisted halogen bonds influenced the parameters and the mechanism of electric conductivity of considered compound.The impedance spectroscopic measurements revealed that the direct current electric conductivity of pentaiodide salt is around four orders of magnitude higher than that of corresponding monoiodide.Moreover,pentaiodide demonstrates the hopping mechanism of conductivity.
