Abstract
- Highlights: ► Plate-like crystals (H{sub 3}N(CH{sub 2}){sub 3}NH{sub 3})[V{sub 4}O{sub 10}] were synthesized. ► Frequency and temperature dependence of AC conductivity indicate CBH model. ► The temperature dependence of DC conductivity exhibits two conduction mechanisms. - Abstract: Layered hybrid compound (H{sub 3}N(CH{sub 2}){sub 3}NH{sub 3})[V{sub 4}O{sub 10}] has been synthesized via hydrothermal method. Techniques X-ray powder diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, and impedance spectroscopy have been used to characterize the hybrid material. Electrical and dielectric properties dependence on both temperature and frequency of the compound have been reported. The direct current conductivity process is thermally activated and it is found to be 12.67 × 10{sup −4} Ω{sup −1} m{sup −1} at 523 K. The spectra follow the Arrhenius law with two activation energy 0.25 eV for T 455 K.
