Abstract

ZusammenfassungUnter Verwendung der Originalvorschrift anstelle der kürzlich vorgeschlagenen neuen Syntheseroute wurde Ce[C8H6(1,4-SiMe3)2]2 (1) als tiefviolettes Öl resynthetisiert. Die Absorptions-, MCD- und Lumineszenzspektren wurden sowohl bei Raumtemperatur als auch bei tiefen Temperaturen gemessen. Vor allem die Tieftemperatur-Spektren sprechen mehr für das Vorliegen einer CeIII-Verbindung.

Using the original and not a newly suggested synthesic route, Ce[C8H6(1,4-SiMe3)2]2 (1) was resynthesized as an oil of deep purple color. The absorption, MCD and luminescence spectra of this compound were measured at room temperature as well as at low temperatures. Especially, the low-temperature spectra are more consistent with a CeIII compound.

Graphical abstractThe low-temperature luminescence, absorption and magnetic circular dichroism spectra of deep purple Ce[C8H6(1,4-SiMe3)2]2 do not contradict results of earlier quantum chemical computations which predict a predominantly trivalent oxidation state of Ce in cerocene.Figure optionsDownload full-size imageDownload as PowerPoint slide
