The preparation and characterization by Raman spectroscopy of Pl4+AsF6– containing the tetraiodophosphonium cation
Abstract
The thermodynamically unstable PI4+AsF6- containing the first and only example of a tetrahedral PI4+4 cation, formally a derivative of the unknown PI5, was prepared by the reaction of PI3 and I3+AsF6– at low temperatures and characterized by Raman spectroscopy.
