The I42+ cation. X-Ray crystal structures of (I42+)(AsF6–)2 and (I42+)(Sb3F14–)(SbF6–)
Abstract
The I42+ cation has been fully characterised for the first time by the preparation of the compounds (I42+)(AsF6–)2 and (I42+)(Sb3F14–)(SbF6–) and the determination of their structures by X-ray crystallography; the I42+ cation has a rectangular structure and may be considered to consist of two I2+ cations held together by two rather weak bonds.
