Pentafluorphenyliod(V)-Verbindungen. 2. Pentafluorphenyliodtetrafluorid C6F5IF4: Synthese durch Fluor-Aryl-Substitution an IF5 — Eigenschaften und Struktur. Strukturanalyse der monovalenten Iodstammverbindung C6F5I

Pentafluorophenyliodine(V) Compounds. 2. Pentafluorophenyliodine Tetrafluoride C₆F₅IF₄: Synthesis via Fluorine-Aryl-Substitution on IF₅ — Properties and Structure. Structural Analysis of the Monovalent Iodine Parent Compound C₆F₅I The nucleophilic fluorine-aryl substitution reaction on IF₅ with pentafluorophenyl, Bi(C₆F₅)₃, leads to C₆F₅IF₄ in good yields and high purity. The thermal stability of C₆F₅IF₄ and its NMR spectrometric behaviour in solution will be described. The crystal structure of C₆F₅IF₄ will be discussed in comparison to IF₅. In addition data of the molecular and crystal structure of the monovalent iodine parent compound C₆F₅I will be given.
