Comprehensive analysis of antimony-based organic-inorganic hybrid material: phase transition, Raman scattering, and the electrical conduction mechanism of [(CH₃)₄P]₃Sb₂Br₉.

ABSTRACT: The present work focuses on elucidating the origin of the phase transition in [(CH₃)₄P]3Sb₂Br₉ and its associated electrical properties. The compound was synthesized by slow solvent evaporation at constant temperature and characterized using X-ray powder diffraction, FTIR spectroscopy, temperature-dependent Raman spectroscopy, and impedance spectroscopy. XRD confirmed the formation of a monoclinic structure with the polar P3₁ c space group. Complementary FTIR and Raman analyses enabled the assignment of vibrational modes at room temperature, providing a reliable reference for monitoring temperature-induced phase transitions. Raman spectra collected between 294 and 563 K revealed specific molecular displacements and reorie
