    Description / Table of Contents: The First Gadolinium Carbide Fluoride: Gd2CF2Gd2CF2, the first gadolinium carbide fluoride is prepared by reaction of stoichiometric amounts of GdF3, Gd, and C at 1250°C in sealed Ta-capsules. It is isotypic with Gd2CBr2 (space group P3m1; a = 373.11(4) and c = 642.5(1) pm). The Gd atoms surround the C atoms octahedrally. Such Gd6C octahedra are condensed via edges to form octahedral sheets, which are separated by double slabs of F-- ions.
    Notes: Mit Gd2CF2 konnte erstmals ein Gadoliniumcarbidfluorid dargestellt werden. Man erhält Gd2CF2 durch Reaktion von stöchiometrischen Mengen GdF3, Gd und C bei 1250°C in verschweißten Ta-Ampullen. Es ist isotyp mit Gd2CBr2 (Raumgruppe P3m1; a = 373,11(4) und c = 642,5(1) pm). Die C-Atome sind von Gd-Atomen oktaedrisch umgeben. Diese Gd6C-Oktaeder sind zweidimensional zu Oktaederschichten kondensiert, die durch F---Doppelschichten voneinander getrennt sind.
