摘要：

A new salt diphenyliodonium triiodide (C12H10I4) was obtained. The [C12H10I+][I (3) (-) ] compound was isolated as red brown crystals and studied by single-crystal X-ray diffraction. The structure of diphenyliodonium triiodide consists of separate, virtually linear I (3) (-) anions and C12H10I+ cations. Strong intermolecular anion-anion (I (3) (-) aEuro broken vertical bar I (3) (-) ) and anion-cation (I (3) (-) aEuro broken vertical bar I+) interactions in the crystal structure leads to a change in the symmetry of triiodide ions. The complex formation in the system organic cation iodide-elementary iodine was studied by spectrophotometry. The complex composition was found (1: 1), and the stability constant of the complex in chloroform was determined (loggB = 3.91).
