On Hexafluorocuprates (III)New prepared are: Cs2LiCuF6 (green, trigonal isotypic to Cs2LiGaF6; a = 621.5, c = 503.3 pm, γ = 120° from CsCuCl3, CsCl, Li2CO3, pF2 = 1 bar, 350°C, 2w); K2LiCuF6 (green, cubic isotypic to K2NaCrF6; a = 792.5 pm from KCuCl3, Li2CO3, KCl, pF2, = 35 bar, 480°C, 3 d); CsRb2CuF6 (green, cubic isotypic to inv. K2NaCrF6; a =899,6 pm from CsCuCl3, RbCl, pF2 = 1 bar, 400°C, 7 d); CsRbKCuF6 (green, cubic isotypic to K2NaCuF6; a = 886.1 pm from KCuCl3, CsCl, RbCl, pF2 = 1 bar, 400°C, 7 d); CsCuCuF6 (black, orthorhombic isotypic to CsNiNiF6; a = 706.7, b = 727.7, c = 1032.2 pm from CsCuCl3, CuCl2 · 2H2O, pF2 = 30 bar, 400°C, 20 h); CsBaCuF6 (green, tetragonal; a = 598.1, c = 864.6 pm from ‚BaCuO2‘, CsCl, pF2 = 350 bar, 400°C, 7 d). Also prepared: Cs2RbCuF6, Cs2KCuF6, Cs2NaCuF6, Rb2KCuF6, Rb2NaCuF6, Rb2LiCuF6, K2NaCuF6, Na3CuF6, K3CuF6, Rb3CuF6, Cs3CuF6 and CsZnCuF6 (parameters see text). The Madelungpart of Lattice Energy, MAPLE are calculated and discussed. All samples are paramagnetic and follow (exception: CsZnCuF6) the Curie-Weiss-Law.
