    Description / Table of Contents: Single Crystal Investigation on AgF2For the first time single crystals of AgF2 (black, metalic bright) have been obtained by heating AgF2 powder under a mixture of HF and F2 in autoclaves at 400°C. It crystallizes orthorhombic in the space group Pbca - D2h15 (Nr. 61) - with a = 556.8(1), b = 583.1(1) and c = 510.1(1) pm; Z = 4.The Madelung Part of Lattice Energy, MAPLE, and the Effective Coordination Number, ECoN, via the Mean Fictive Ionic Radii, MEFIR, are calculated and discussed.
    Notes: Erstmals wurden schwarze, metallisch glänzende Einkristalle von AgF2 durch Erhitzen des mikrokristallinen AgF2 dargestellt (Monel-Autoklaven, T ≈ 400°C, HF/F2-Gemisch, 4 d). Die röntgenographische Untersuchung (a = 556,8(1); = 583,1(1); c = 510,1(1) pm; Z = 4; Parameter siehe Text) bestätigt die aus Neutronenbeugungsuntersuchung ermittelte Raumgruppe Pbca - D2h15 (Nr. 61) und ergibt Lageparameter, die mit den damals ermittelten Werten praktisch übereinstimmen. Der Madelunganteil der Gitterenergie, MAPLE, sowie Effektive Koordinationszahlen, ECoN, werden über Mittlere Fiktive Ionenradien, MEFIR, berechnet und diskutiert.
