摘要

We report on some electrical properties and solid-solid phase transitions of organic-inorganic hybrid layered halide perovskite and intercalated compound (n-C12H25NH3)(2)ZnCl4 which is one member of the long-chain compounds of the series (n-CnH2n+1NH3)(2,)(n = 8-18). The complex dielectric permittivity epsilon*(omega,T) and the ac conductivity sigma (omega,T) were measured as functions of temperature 100 K < T < 390 K and frequency 5 kHz < f < 100 kHz. Moreover, the differential scanning calorimetery and the differential thermal analysis thermograms were performed. The analysis of our data confirms the existence of a structural phase transition at T approximate to (362 +/- 2) K, where the compound changes its state from intercalation to non-intercalation with a drastic increase in the c-axis by about 16.4%.
