This study delves into the electrical characteristics of vanadium complexes obtained from acyl-hydrazone ligands. Impedance spectroscopy, a technique that spans a broad spectrum of frequencies and temperatures, aimed to to elucidate the relationship between temperature-induced structural transformations and the electrical conductivity of the materials under investigation. The analysis is further supported by temperature-dependent X-ray powder diffraction and thermogravimetric data, enhancing the precision of the measurement optimisation process.

Given the scant representation of vanadium coordination compounds as semiconductors in existing literature, this research offers novel insights that promise to deepen the scientific community's comprehension of this class of materiala. Additionally, the study explores the optical characteristics of vanadium-based materials, identifying impedance spectroscopy as a valuable method for real-time observation of the coordination complexes' transitions. The findings suggest that these materials possess considerable potential for application as semiconductors in a variety of electronic devices.
