Organic-inorganic hybrid materials have recently found a vast variety of applications in the fields of energy storage and microelectronics due to their outstanding electric and dielectric characteristics, including high dielectric constant, low conductivity, and low dielectric loss. However, despite the promising properties of these materials, there remains a need to explore novel compounds with improved performance for practical applications. In this research paper, the focus is on addressing this scientific challenge by synthesizing and characterizing the new-centrosymmetric (CHN)[CdBr] crystal.

The frequency and temperature-related dielectric relaxation and electrical conduction mechanisms in potassium-doped CaFeO oxide ceramic were investigated in this study throughout a temperature range of 313-673 K. The synthesis of the KCaFeO compound was accomplished through a solid-state reaction route. The X-ray diffraction pattern at room temperature confirmed that the ceramic KCaFeO crystallizes in the orthorhombic system with the space group.
