Über Metaferrate(IV)

Abstract: Die Metaferrate(IV) des Strontiums und Bariums erhält man am besten, wenn man von den Ferraten(IV) ausgeht. Li2FeO3 kann durch thermische Umsetzung von K2FeO4 mit LiOH dargestellt werden. Bei der Fällung von K2FeO4‐Lösung mit AgNO3 entsteht nicht Silberferrat(VI), sondern Silbermetaferrat(IV) Ag2FeO3 · aq. Die Eigenschaften dieser Metaferrate(IV) werden beschrieben.

“…Strontium ferrates with iron in the oxidation state #4 form a Ruddlesden-Popper-type series of compounds having the general formula Sr L> Fe L O L> with n"1 (Sr FeO (1)), 2 (Sr Fe O (2, 3)), or R (SrFeO (4,5)). The basic units building up the crystal structures of these compounds are regular or nearly regular FeO octahedra which are connected via common corners to form two-dimensional iron-oxygen layers in the K NiF -type structure of Sr FeO but a three-dimensional network in the cubic perovskite SrFeO .…”

“…Weitere Ferrate(VI) sind in der Literatur beschrieben [15], deren Existenz aber bis auf die von BaFeO 4 , welches als Monohydrat aus wa È ûriger Lo È sung ausfa È llt, umstritten oder widerlegt worden ist. So konnte weder die Darstellung von Calcium-, Cobalt(II)-, Blei(II)-, Quecksilber(II)-, Eisen(III)-oder Zinkferraten(VI) reproduziert werden [16] noch fu È hrt die Umsetzung von K 2 FeO 4 mit AgNO 3 in wa È ûriger Lo È sung zu Ag 2 FeO 4 , sondern unter spontaner Sauerstoffabgabe zu Ag 2 FeO 3 [17].…”
