Abstract

Zellkonstanten und Raumgruppe der Verbindungen Fe(C5H5)2, Co(C5H5)2 und Ni(C5H5)2 werden bestimmt. Nach der Ähnlichkeit dieser Konstanten, der Zugehörigkeit der drei Verbindungen zur selben Raumgruppe und dem gleichen Gang der Intensitäten aller Röntgenreflexe liegt bei Co(C5H5)2 und Ni(C5H5)2 die gleiche Struktur vor wie bei Fe(C5H5)2. Ein Vergleich der Zelldimensionen der drei Verbindungen untereinander mit den Differenzen der oktaedrischen Kovalenzradien der entsprechenden Metalle liefert einen Hinweis auf das Vorliegen oktaedrischer Bindungen.
