    Description / Table of Contents: Synthesis and Structure of Tetrafluoroaurates(III) MI[AuF4] with MI = Li, RbSingle crystal investigations on Rb[AuF4], light yellow, confirm the tetragonal unit cell (K[BrF4]-type) with a = 618.2(1) and c = 1191(1) pm, Z = 4, space group I 4/mcm-D4h18 (No. 140).Li[AuF4], light yellow too, crystallizes monoclinic with a = 485.32(7), b = 634.29(8), c = 1004.43(13) pm, β = 92.759(12), Z = 4; space group P 2/c-C2h4 (No. 13).

    Description / Table of Contents: On the Crystal Structure of MnF3 and MnPtF6Single crystal investigations of MnF3 (rubyred) confirmed the crystal structure based on powder data [2]: monoclinic, space group C 2/c-C2h6 (No. 15) with a = 892.02 pm, b = 504.72 pm, c = 1 347.48 pm, β = 92.64° with Z = 12.The corresponding determination of the crystal structure of MnPtF6, yellow, confirmed the unit cell [3] with a = 510.47 pm, c = 1 421.0 pm and γ = 120°, Z = 3 space group R 3-C3i2 (No. 148).For both compounds detailed parameters respectively interatomic distances have been obtained.
    Notes: Einkristalluntersuchungen an MnF3 (rubinrot) bestätigen den aus Pulverdaten [2] abgeleiteten Strukturvorschlag: monoklin, Raumgruppe C 2/c-C2h6 (Nr. 15) mit a = 892,02 pm, b = 504,72 pm, c = 1 347,48 pm, β = 92,64° mit Z = 12 (Vierkreisdiffraktometerdaten).Entsprechende Einkristalluntersuchungen an MnPtF6, hellgelb, bestätigen auch hier die Abmessungen der Elementarzelle [3] mit a = 510,47 pm, c = 1 421,0 pm und γ = 120°, Z = 3 in der Raumgruppe R °3-C3i2 (Nr. 148).

    Description / Table of Contents: On the Crystal Structure of SmZrF7 with an Appendix on EuSnF7 and YSnF7SmZrF7 again was obtained as colourless single crystals and investigated by X-ray methods: It crystallizes in space group P 21/c-C2h5 (Nr. 14; P 21/n) with a = 1 140.9(2) pm, b = 574.6(1) pm, c = 914,4(2) pm, β = 107.32(2)°, Z = 4 but not in space group P 21-C22 (Nr. 4) [1]. In addition EuSnF7 and YSnF7 are isotypic with the following lattice constants: EuSnF7: a = 1 121.8(2) pm, b = 563.7(1) pm, c = 901.7(1) pm, β = 107.35(2)° with Z = 4; YSnF7: a = 1 106.7(2) pm, b = 556.4(1) pm, c = 884.7(1) pm, β = 107.51(1)° and Z = 4 (Powder data).
    Notes: SmZrF7 wurde erneut in Form farbloser Einkristalle dargestellt und röntgenographisch untersucht: Danach kristallisiert es in der Raumgruppe P 21/c-C2h5 (Nr. 14; Aufstellung P 21/n) mit a = 1 140,9(2) pm, b = 574,6(1) pm, c = 914,4(2) pm, β = 107,32(2)°, Z = 4, also nicht in der Raumgruppe P 21-C22 (Nr. 4) [1]. Aufgrund neuer Strukturrechnungen kristallisieren EuSnF7 und YSnF7 ebenfalls in der zentrosymmetrischen Raumgruppe P 21/c-C2h5 (Nr. 14) mit folgenden Gitterkonstanten für EuSnF7: a = 1 121,8(2) pm, b = 563,7(1) pm, c = 901,7(1) pm, β = 107,35(2)° mit Z = 4 sowie für YSnF7 a = 1 106,7(2) pm, b = 556,4(1) pm, c = 884,7(1) pm, β = 107,51(1)° und Z = 4 (Pulverdaten).

    LiSmAlF6  -  das erste Fluoroaluminat mit zweiwertigem Samarium (1991)

    Description / Table of Contents: LiSmAlF6  -  the First Fluoroaluminate with Divalent SamariumLiSmAlF6, the first quaternary fluoride with Sm2+ that has been obtained as red transparent single crystals, is formed while heating corresponding mixtures of the starting materials in niobium or tantalum crucibles under argon after 7-10 d at about 800°C. Orange-red, microcrystalline powder samples of LiSmAlF6 could be prepared at T ≤ 700°C after 1-2 d under the same conditions.LiSmAlF6, crystallizes as a new structure type in P6322 (Nr. 182) with a = 507.9(1), c = 1 040.5(1) pm and Z = 2 (CAD4, 2 512 Io, Rw = 2,3%). The crystal structure of LiSmAlF6 is related to the LiCaAlF6 structure type whereby the essential difference lies in the coordination of the M2+ ions. Ca2+, as well as Sr2+ in LiSrAlF6, exhibit octahedral coordination, whereas Sm2+ has, surprisingly, trigonal prismatic coordination to F-. The two triangles of the SmF6 prism are twisted by 8.3° with respect to each other.Measurements of the magnetic susceptibility show the temperature dependence typically found for Sm2+. The Madelung part of the lattice energy has been calculated and is discussed.
    Notes: LiSmAlF6, das erste in Form roter, transparenter Einkristalle erhaltene quaternäre Fluorid mit Sm2+, bildet sich beim Erhitzen geeigneter Ausgangsmenge in Niob- oder Tantaltiegln unter Ar nach 7-10 d bei ca. 800°C. Orangerote, mikrokristalline Pulverproben von LiSmAlF6 können bei T ≤ 700°C bereits nach 1-2 Tagen unter sonst gleichen Bedingungen dargestellt werden.LiSmAlF6 kristallisiert in einem neuen Strukturtyp in P6322 (Nr. 182) mit a = 507,9(1), c = 1 040,5(1) pm und Z = 2(CAD4, 2 512 Io, Rw = 2,3%). Die Kristallstruktur von LiSmAlF6 ist dem LiCaAlF6-Typ verwandt, zeigt aber den wesentlichen Unterschied in der Umgebung für M2+ : Ca2+, wie auch Sr2+ in LiSrAlF6, werden oktaedrisch, Sm2+ jedoch überraschenderweise trigonal-prismatisch von F- koordiniert. Die beiden Dreiecke des SmF6-Prismas sind um 8,3° gegeneinander verdreht.Messungen der magnetischen Suszeptibilität zeigen die für Sm2+ typische Temperaturabhängigkeit. Der Madelunganteil der Gitterenergie wurde berechnet und diskutiert.
