Preparation, Characterization, and Theoretical Study of Nanoparticles of Triphenylphosphonium Tetrachloroaluminate(III) [P(C₆H₅)₃H]⁺[AlCl₄]⁻

Abstract

Triphenylphosphonium tetrachloroaluminate(III) [P(C₆H₅)₃ H]⁺[AlCl₄]⁻, TPPTCA, nanoparticle was synthesized by using triphenylphosphonium chloride addition to AlCl₃ in the presence of surfactant. The product was characterized by spectroscopic and analytical methods such as ³¹P-NMR, FT-IR, XRD, SEM, and CHN. Theoretical calculations were used for the structural optimization of this compound. The structure of compound has been calculated and optimized by the density functional theory (DFT) based method at B3LYP/6–311G levels of theory, using the Gaussian 03 package of programs. The comparison between theory and experiment is made. On the base of the application of scanning electron microscopy is showed about 54 nm particle sizes.
