    Description / Table of Contents: Fe(OTeF5)3, Preparation, Structure, and ReactivityFeCl3 reacts with ClOTeF5 under formation of Fe(OTeF5)3. From SO2ClF solutions an adduct Fe(OTeF5)3 · 3SO2ClF can be crystallized. This has a distorted octahedral iron oxygen co-ordination. The solvate-free compound is trigonal-planar, according to its Mößbauer spectrum. It has an extreme reactivity towards bases. Only alkanes and perfluoro-alkanes remain unaffected. Attempts to coordinate P(OC2H5)3 in SO2ClF solution result in a complex reaction under formation of [P(OC2H5)4]+ [Te2Cl9]- and iron fluoride(s).
    Notes: FeCl3 reagiert mit ClOTeF5 unter Bildung von Fe(OTeF5)3. Aus der Lösung in SO2ClF kristallisiert ein Addukt Fe(OTeF5)3 · 3SO2ClF mit verzerrt oktaedrischer Eisen-Sauerstoff-Koordination. Die solvatfreie Verbindung ist nach Mößbauermessungen anscheinend trigonal planar aufgebaut und zeigt ein extremes Reaktionsverhalten gegenüber Basen: Nur Alkane und Perfluoralkane werden nicht angegriffen. Versuche zur Komplexierung der freien Koordinationsstellen z. B. mittels P(OC2H5)3 in SO2ClF-Lösung ergaben in komplexer Reaktion [P(OC2H5)4]+[Te2Cl9]- und Eisenfluorid.
