    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).

    Description / Table of Contents: Synthesis and Structure of Silver(II) Tetrafluoroaurate(III) Ag[AuF4]2Intensive green single crystals of Ag[AuF4]2 can be obtained by heating up micro crystalline Ag[AuF4]2 in autoclaves (p(F2) ∼ 200 bar, T ∼ 400°C, t ∼ 14 d). It crystallizes monoclinic, space group P21/n — C2h5; (No. 14) with a = 522.3(1), b = 1101.3(3), c = 550.5(2) pm, β = 94.98(3), Z = 2 and is isotypic with Pd[AuF4]2.
    Notes: Durch Tempern mikrokristalliner Ag[AuF4]2-Proben im Autoklaven (p(F2) ∼ 200 bar, T ∼ 400°C, t ∼ 14 d) wurden leuchtend grüne Einkristalle von Ag[AuF4]2 erhalten. Die Verbindung kristallisiert monoklin, in der Raumgruppe P21/n — C2h5; (Nr. 14) mit a = 522.3(1), b = 1101.3(3), c = 550.5(2) pm, β = 94.98(3)°, Z = 2 und ist isotyp zu Pd[AuF4]2.

    Description / Table of Contents: Synthesis and Structure of MII[AuF4]2 with MII = Ni, PdYellow Ni[AuF4]2, obtained as single crystals by solvothermal synthesis in anhydrous HF crystallizes monoclinic, isotypic to M[AuF4]2 (M = Mg, Zn) [1], space group P21/c-C2h5 (No. 14) with a = 550.4, b = 546.0, c = 1083.1 pm and β = 109.47°. In order to get better comparison to Pd[AuF4]2 it will be described in the space group P21/n with a = 550.4 pm, b = 546.0 pm, c = 1038.2 pm, β = 100.47° and Z = 2. Green Pd[AuF4]2, prepared by heating a mixture of PdF2 and AuF3 in sealed Au-tubes crystallizes also monoclinic, space group P21/c (setting P21/n with a = 519.79 pm, b = 1095.7 pm, c = 555.7 pm, β = 89.93° and Z = 2), but it is not isotypic to Ni[AuF4]2.

P21/c-C2h5 (Nr.14) mit a = 550.4, b = 546.0, c = 1083.1 pm und β = 109.47°. Wegen des besseren Vergleichs mit Pd[AuF4]2 wird es im folgenden ebenfalls in der Aufstellung P21/n mit a = 550.4 pm, b = 546.0 pm, c = 1038.2 pm, β = 100.47° und Z = 2 beschrieben.Grünes Pd[AuF4]2, dargestellt aus den binären Komponenten PdF2 und AuF3 kristallisiert ebenfalls in der Raumgruppe P21/c (Aufstellung P21/n mit a = 519.79 pm, b = 1095.7 pm, c = 555.7 pm, β = 89.93° und Z = 2), ist jedoch nicht isotyp mit Ni[AuF4]2.
