Abstract
Die vorliegende Dissertation befaßt sich mit der Darstellung und Charakterisierung von polyvalenten Iod-Verbindungen. Der erste Teil beschreibt trifluormethyl-substituierte Iod(III)-Moleküle des Typs CF3IX2 (X = F, Cl, OCH3, OCOCF3) und CF3I(Cl)Y (Y = F, OCH3, OCOCF3). Anhand der in Einkristallröntgenstrukturuntersuchungen ermittelten Bindungsdaten wird ein Prinzip zur Beschreibung der Bindungsverhältnisse in den Verbindungen diskutiert.
Neben der gemischt-valenten Verbindung Cl2IOI(O)F2 umfaßt der zweite Teil Moleküle mit Iod in der Oxidationsstufe (V). Im dritten Kapitel wird mit [PPh4] [I3Br4] exemplarisch das Gebiet der Polybromide angeführt.
Syntheses and characterisation of polyvalent iodine compounds are described. The first part deals with trifluoromethyl substituted iodine(III) compounds CF3IX2 (X = F, Cl, OCH3, OCOCF3) and CF3I(Cl)Y (Y = F, OCH3, OCOCF3). By using bond lengths and data obtained by single crystal X-ray structure determination, a principle to describe bond parameters in these compounds is discussed. In addition to the mixed valent compound Cl2IOI(O)F2, molecules containing iodine in the oxidation state (V) are described in the second part. With [PPh4] [I3Br4] an example of a polybromide is reported.
