Abstract: | The reported crystal structures of Ph4P+·I? and Ph4As+·I? have been re‐examined. An apparent instance of substitutional dimorphism could not be reproduced and, contrary to an earlier report, tetraphenylarsonium iodide, As(C6H5)4]I or Ph4As+·I?, was found to be isostructural with the phosphorus compound. The cation and anion are both located on symmetry sites. The crystal packing involves linear chains of cations in fourfold phenyl embraces. |
