High temperature structural phase transition and dielectric relaxation in an organic–inorganic hybrid compound: (4-methylpiperidinium)CdCl3

Author affiliations

Abstract

A new organic–inorganic hybrid perovskite-type compound, (4-MPD)CdCl3 (1, 4-MPD = 4-methylpiperidinium), demonstrating high temperature phase transition at around 364 K and prominent dielectric relaxation behavior, can be considered as a potential high temperature relaxor-type dielectric material. Systematic characterization techniques have been performed including variable-temperature structural analyses, differential scanning calorimetry (DSC) measurements, dielectric measurements and powder X-ray diffraction (PXRD) measurements. The structural phase transition coupled with the dielectric relaxation property is mainly ascribed to the order–disorder changes of organic cations. The studies of dielectric relaxation between 25 kHz and 1000 kHz disclose a significant Debye relaxation process above room temperature, which is well fitted by the Cole–Cole function.
