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 Ramanspectroscopy.

The solid state structure of the [(CH3CN)(2)I](+) cation in [(CH3CN)(2)I][AsF6] was determined using single crystal X-ray diffraction. The highly reactive cation was prepared by reaction of [I-3][AsF6] with CH3CN in liquid SO2. In the solid state, the CNI backbone consisting of seven atoms is linear and shows a dicoordinate iodine center. The ability of [I-3][AsF6] to act as a source of "[I](+)" to CH3CN and N2O is compared, and the computed structures of the [CH3CNI](+), [(CH3CN)(2)I](+), [IN2O](+) and [ION2](+) cations are discussed.
