    Description / Table of Contents: Jahn-Teller Effect and Crystal Structure Distortion of the Copper Fluoroperovskites NaCuF3 and RbCuF3The crystal structures of triclinic NaCuF3 (a = 539.1, b = 555.2, c = 792.8 pm, α = 90.66, β = 92.05, γ = 86.95°; P1, Z = 4) and of tetragonal RbCuF3, isotypic with KCuF3, (a = 602.3, c = 791.2 pm; I4/mcm, Z = 4), were determined by x-ray methods and refined to wR = 0.038 (2113 reflections) resp. 0.039 (257 reflections). The structures derive from orthorhombic (GdFeO)3 and cubic perovskite type, resp., by Jahn-Teller distortion. The CuF64- octahedra, differently elongated in the two compounds (average NaCuF3: Cu—F = 188.9/197.3/225.6(2) pm; RbCuF3: 188.3/197.8/237.6(3) pm), show the same pattern of antiferrodistortive ordering, but there are bent bridges Cu—F—Cu = 144.2…148.0(1)° in NaCuF3. Structural relations to the prototypes mentioned and to comparably Jahn-Teller distorted copper fluoro compounds are discussed.
    Notes: Die Kristallstrukturen des triklinen NaCuF3 (a = 539,1, b = 555,2, c = 792,8 pm, α = 90,66, β = 92,05, γ = 86,95°; P1, Z = 4) und des tetragonalen, mit KCuF3 isotypen RbCuF3 (a = 602,3, c = 791,2 pm; I4/mcm, Z = 4) wurden röntgenographisch bestimmt und auf wR = 0,038 (2113 Reflexe) bzw. 0,039 (257 Reflexe) verfeinert. Die Strukturen leiten sich vom orthorhombischen (GdFeO3-) bzw. kubischen Perowskit-Typ durch Jahn-Teller-Verzerrung ab. Die in beiden Verbindungen unterschiedlich gestreckten CuF64--Oktaeder (Mittelwert NaCuF3: Cu—F = 188,9/197,3/225,6(2) pm; RbCuF3: 188,3/197,8/237,6(3) pm) sind nach demselben Muster antiferrodistortiv geordnet, jedoch unter Winkelung Cu—F—Cu = 144,2…148,0(1)° in NaCuF3. Strukturelle Beziehungen zu den genannten Prototypen und zu vergleichbar Jahn-Teller-verzerrten Kupfer-Fluorverbindungen werden diskutiert.

    Description / Table of Contents: Structures of Cesium-containing Fluorides. V. Pseudohexagonal Tungsten Bronze Structure of the Monoclinic Phase Cs0.4Zn0.4Fe1.6F6 and Related Cesium Transition Metal FluoridesThe crystal structure of the pseudohexagonale phase Cs0.4Zn0.4Fe1.6F6 was refined in the monoclinic space group P21 (a = 747.4, b = 763.6, c = 746.1 pm, β = 120.0°, z = 3). Using 1067 single crystal reflections R = 6.3% was reached. Compared to the hexagonal tungsten bronze structure the corner-sharing of octahedra shows pronounced angles also along the unique axis (M—F—M = 159.0°). The average bridge angle in the framework of tilted octahedra is 149.6°. Structural relations are discussed.
    Notes: Die Kristallstruktur der pseudohexagonalen Phase Cs0,4Zn0,4Fe1,6F6 konnte in der monoklinen Raumgruppe P21 (a = 747,4 b = 763,6, c = 746,1 pm, β = 120,0°, z = 3) unter Auswertung von 1 067 Einkristallreflexen auf R = 6,3% verfeinert werden. Im Vergleich zur Struktur der hexagonalen Wolframbronzen ist die Oktaeder-Eckenverknüpfung auch längs der ausgezeichneten Achse deutlich gewinkelt (M—F—M = 159,0°). Der mittlere Brückenwinkel im Raumnetz der verkippten Oktaeder beträgt 149,6°. Die Strukturverhältnisse werden diskutiert.

    Description / Table of Contents: Lattice Constants and Ionic Radii of Pyrochlores CsMIIMIIIF6From observed lattice constants a0 of 30 cubic pyrochlores CsMIIMIIIF6 (MII = Mg, Ni, Cu, Zn, Co, Mn; MIII = Ga, Cr, Fe, V, Ti) balanced values ac were calculated, which deviate in average less than 0.1% from the observed ones. Radii rc of the M(II) and M(III) ions are evaluated from the balanced values ac by means of an empiric equation; they reproduce the lattice constants a0 equally well. By analogy derived radii rII and rIII from additional pyrochlores CsMIIMIIIF6 are given and discussed in comparison with tabulated radii and observed M—F distances.
    Notes: Aus den beobachteten Gitterkonstanten a0 von 30 kubischen Pyrochloren CsMIIMIIIF6 (MII = Mg, Ni, Cu, Zn, Co, Mn; MIII = Ga, Cr, Fe, V, Ti) werden Ausgleichswerte ac gebildet, die im Mittel weniger als 0,1% von den Beobachtungsgrößen abweichen. Aus den Ausgleichswerten ac werden mit Hilfe einer empirischen Beziehung Radien rc für die M(II)- und M(III)-Ionen abgeleitet, mit denen die Gitterkonstanten a0 mit entsprechender Genauigkeit reproduzierbar sind. Analog aus weiteren Pyrochloren CsMIIMIIIF6 ermittelte Radien rII und rIII werden mitgeteilt und im Vergleich mit tabellierten Radien und beobachteten M—F-Abständen diskutiert.
