Über Fluoride des zweiwertigen Eisens. Zum Aufbau von CsFeF3

Abstract: Durch „Reaktion mit der Wand”︁ gelang es, erstmals unter striktem Ausschluß von Sauerstoff, gemäß 3 CsF + 2 FeF3 + FeWand = 3 CsFeF3 farblose Einkristalle von CsFeF3 zu erhalten. Die Gitterkonstanten wurden mit a = 616,39(6), c = 1487,02(15) pm (Vierkreisdiffraktometer PW 1100, AgK\documentclass{article}\pagestyle{empty}\begin{document}$ \bar \alpha $\end{document}, R = 4,33% und Rw = 2,79%) neu bestimmt. CsFeF3 kristallisiert isotyp zu BaTiO3(hexagonal) in der Raumgruppe P63/mmc. Parameter siehe Text. Der Mad… Show more

“…The hexagonal ABF 3 perovskites, studied for their ferrimagnetic properties, are the main representatives of this class of compounds ( a H ≈ 6.0 Å). Generally, several polytypes exist, 2L ( c H = 5.24 Å, P 6 3 / mmc for CsNiF 3 ), 6L ( c H = 14.88 Å, P 6 3 / mmc for CsFeF 3 ), or 9L ( c H = 22.64 Å, R 3̅ m for CsCoF 3 ). Only the 2L polytype exhibits [MF 3 ] chains (Figure d) (cf.…”
