    Description / Table of Contents: Synthese und Eigenschaften der fünfwertigen Antimon- und BismutfluorideEinige Eigenschaften der SbV- und BiV-fluoride, speziell die Systeme MIIF2-MvF5 (Mv = Sb, Bi; MII = Mg, Ca, Sr, Ba) und HalF3-BiF5 (Hal = Cl, Br) wurden untersucht. Es bilden sich nur Verbindungen der Zusammensetzung MII(MvF6)2 bzw. HalF2[BiF6], die in ihren Kristallgittern oktaedrische Anionen MvF6- enthalten. Die bezüglich BiF5 stärkere Lewissäure SbF5 keine Polyfluoride vom Typ M2vFII- und andere. Die Temperaturabhängigkeit und die chemische Umwandlung des fünfwertigen Antimon- und Bismutfluorids wurden untersucht.
    Notes: Properties of Sbv and Biv fluorides and MIIF2-MvF5 (Mv = Sb, Bi; MII = Mg, Ca, Sr, Ba), HalF3-BiF5 (Hal = Cl, Br) systems have been studied. Only MII(MvF6)2 and HalF2[BiF6] are shown to be formed in these systems. MII(MvF6)2 and HalF2[BiF6] contain MvF6-octahedra in their crystal lattices. SbF5 is found to be a stronger Lewis acid than BiF5 and to be capable to substitute the latter in its fluoro complexes. BiF5, in contrast to SbF5, does not form polyfluoro anions (e.g.M2vF11-etc.). The thermal stability of Sbv and Biv fluorides and their transformations at high temperature were studied.
