    Description / Table of Contents: Kristallstruktur von Pb7FeIIFe6IIIF34: eine neue Jarlit-Typ VerbindungDie Kristallstruktur von Pb7FeIIFe6IIIF34 wurde aus Einkristalldaten bestimmt: monoklin, Raumgruppe C2/m (Nr. 12), a = 16,375(2), b = 11,233(2), c = 7,615(1) Å, β = 102,67(1)º, Z = 2; 957 unabhängige Reflexe, davon 705 mit F/σ(F) 〉 4 ergeben einen R-Wert von 0,038. Die Verbindung besteht aus unendlichen, spiralförmigen [FeIIFe6IIIF34]n14n--Doppelketten eckenverknüpfter Oktaeder entlang der b-Achse, die voneinander durch Blei-Ionen getrennt sind.
    Notes: Pb7FeIIFe6IIIF34 is monoclinic: a = 16.375(2) Å, b = 11.233(2) Å, c = 7.615(1) Å, β = 102.67(1)º, Z = 2. The crystal structure was solved in the space group C2/m (nº 12), from X-ray single crystal data using 957 independent reflections (705 with F/σ(F) 〉 4, leading to R = 0.038). It consists in infinite helicoidal [FeIIFe6IIIF34]n14n- double-chains of cornersharing octahedra running along the b-axis and separated from each other by lead ions.
