    Description / Table of Contents: Hitherto unknown BaAgF4 (a = 6.038, c = 11.46 Å), SrAgF4 (a = 5.739, c = 11.12 Å), CaAgF4 (a = 5.493, c = 10.86 Å), CdAgF4 (a = 5.423, c = 10.80 Å) and HgAgF4 (a = 5.524, c = 10.92 Å) are prepared. GUINIER patterns show, that all compounds are isostructural with tetragonal K[BrF4]. All compounds are deeply coloured and obey the CURIE-WEISS law (μ ≈ 1.9 μB). The MADELUNG part of lattice energy (MAPLE) is discussed.
    Notes: Neu dargestellt wurden BaAgF4 (a = 6,038, c = 11,46 Å), SrAgF4 (a = 5,739, c = 11,12 Å), CaAgF4 (a = 5,493, c = 10,86 Å), CdAgF4 (a = 5,423, c = 10,80 Å) und HgAgF4 (a = 5,524, c = 10,92 Å). Nach GUINIER-Aufnahmen liegt Isotypie mit tetragonalem K[BrF4] vor. Alle Verbindungen sind intensiv farbig und befolgen das CURIE-WEISS-Gesetz (μ ≈ 1,9 μB). Der MADELUNG-Anteil der Gitterenergie (MAPLE) wird diskutiert.

    Description / Table of Contents: Magnetochemistry of Divalent Silver. New Fluoroargentates(II): Cs2AgF4, Rb2AgF4, and K2AgF4Hitherto unknown blue compounds Rb2AgF4 and Cs2AgF4 are prepared. Guinier patterns show, that Cs2AgF4 cristallise in the K2NiF4 structure (a = 4.581, c = 14.192 Å). The structure of the Rb-compound is still unknown. The magnetic behaviour of K2AgF4, Rb2AgF4, and Cs2AgF4 is discussed.
    Notes: Neu dargestellt wurden die blauen Verbindungen Rb2AgF4 und Cs2AgF4. Nach Guinier-Aufnahmen kristallisiert Cs2AgF4 tetragonal (a = 4,581, c = 14,192 Å) und ist mit K2NiF4 isotyp. Die Struktur von Rb2AgF4 ist bislang unbekannt. Über den Magnetismus von K2AgF4, Rb2AgF4 und Cs2AgF4 wird berichtet.

    Description / Table of Contents: Magnetochemistry of Fluoroargentates(II): Investigation of Ba[AgF4], Sr[AgF4], Ba2AgF6, K[AgF3], and Cs[AgF3]Ba[AgF4] (Θ = -4 K, μ = 1.92 μB), isostructural with K[BrF4] with planar [AgF4] groups, fullfil the Curie-Weiss-law, also Ba2AgF6 (Θ = 4 K, Θ = 1.85 μB) which is related with the structure of Ba2CuF6. The variante of perovskite-type K[AgF3] (orthorhombic) and Cs[AgF3] (tetragonal perovscite) show collective magnetic interactions (TN = 80 K, KAgF3, and 50 K, CsAgF3) and show a behaviour like AgF2 (TN160 K) correspondingly to the magnetic dilution. Above TN paramagnetism is nearly independend of tempearture.
    Notes: Ba[AgF4] (Θ = -4K, μ = 1,92μB), Sr[AgF4] (μ = -6 K, μ = 1,78μB) und Hg[AgF4] (Θ = -6 K, μ = 1,86 μB), Vertreter des K[BrF4]-Typs mit planaren [AgF4]-Gruppen, befolgen das Curie-Weissche Gesetz, ebenso Ba2AgF6, strukturell mit Ba2CuF6 verwandt (Θ = +4 K, μ = 1,85 μB). Die Perowskit-Varianten K[AgF3] (orthorhombisch) und Cs[AgF3] (tetragonaler Perowskit) zeigen kollektive magnetische Wechselwirkungen (TN = +80 K, KAgF3, bzw. +50 K, CsAgF3) und lehnen sich, der magnetischen Verdünnung entsprechend, an AgF2 (TN = 160 K) an. Oberhalb TN tritt praktisch temperaturunabhängiger Paramagnetismus (μ ≈ 1,0 μB) auf.
