Preparation and characterization of a new halo chromate nanoparticle: Triphenylphosphonium trifluoroiodochromate (III)[P(C۶H۵)۳H]+[CrF۳I]-

A new mixed  halo chromate  nanoparticle compound was synthesised and characterized. Triphenylphosphonium trifluoroiodochromate (III)[P(C۶H۵)۳H]+[CrF۳I]- nanoparticle was synthesized by using triphenylphosphonium  iodide reaction with CrF۳, in the presence of  ۳-mercaptopropionic acid. This method is a simple and direct method. The product was characterized by spectroscopic and analytical methods such as ۳۱P-NMR, FT-IR, XRD, SEM. 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 B۳LYP/۶-۳۱۱G levels of theory, using the Gaussian ۹۸ package of programs. The comparison between theory and experiment is made. On the base of application of scanning electron microscopy (SEM) is showed about ۵۴ nm particle sizes.
