Optical and electric properties of the organic-inorganic hybrid bis (2-amino-5-picolinium) Tetrachlorocobaltate(II) [(C6H9N2)2CoCl4]

Organic-inorganic hybrid materials have garnered considerable interest due to their unique physical and chemical properties, enabling their use in diverse applications. This study explores the synthesis and characterization of the organic-inorganic hybrid compound (C6H9N2)2CoCl4. The compound was successfully synthesized via the slow evaporation method at room temperature. The X-ray diffraction on a single crystal indicated a monoclinic structure in the P21/c space group. Various analytical techniques were employed to ensure the material's high purity and to investigate its properties. Powder X-ray diffraction and SEM/EDX analysis confirmed the compound's crystalline structure and elemental composition. Raman spectroscopy provided insights into the vibrational characteristics. In contrast, UV-visible absorption and luminescence spectroscopy were used to explore its optical properties, indicating its potential as a semiconductor. The electrical and dielectric properties were studied using complex impedance spectroscopy (CIS), revealing significant frequency and temperature dependence. Additionally, Kohlrausch-Williams-Watts analysis was employed to examine the electric modulus, further elucidating the compound's non-Debye behavior. These methods collectively demonstrate the compound's potential applications in electronic and optical devices.
