    Description / Table of Contents: About the Na5[GaO4]-Relationship: KNa4[GaO4] and CsK4[GaO4]KNa4[GaO4] was newly prepared from binary oxides (powders) and also from KGaO2/Na2O/K2O (colourless columnar single crystals) in a closed Ag-cylinder at 600 and 650°C. Space group Pbca with a = 1046.1(2), b = 596.3(1), c = 1871.1(3) pm, Z = 8 [Four-circle-diffractometer data, 1138 I0(hkl), MoKα, R = 8.29, Rw = 6.76%, anisotropic refinement] (Parameter s. text).Colourless cubic single crystals of hitherto unknown CsK4[GaO4] are formed by reaction of K2O, CsGaO2, and Cs2O (surplus) in a closed Au-tube at 580°C. Space group Pbca with a = 1154.7, b = 667.7, c = 2096.6 pm, Z = 8 [Four-circle-diffractometer data, 1798 I0(hkl), MoKα, R = 7.62, Rw = 7.68%, anisotropic refinement] (Parameter s. text). Both crystal structures belong to the Na5[GaO4] type. Structural aspects, ECoN, and MAPLE of KNa4[GaO4] and CsK4[GaO4] in relation with Na5[GaO4] are discussed.
    Notes: Neu dargestellt wurde KNa4[GaO4] aus den binären Oxiden (Pulver) bzw. aus Gemengen von KGaO2/K2O/Na2O (säulenförmige farblose Einkristalle) in einem geschlossenen Ag-Bömbchen bei 600 bzw. 650°C. Es liegt die RGr. Pbca mit a = 1046,1(2), b = 596,3(1), c = 1871,1(3) pm, Z = 8 vor. [Vierkreisdiffraktometerdaten, 1138 I0(hkl), MoKα, R = 8,29%, Rw = 6,76%, anisotrope Verfeinerung] (Parameter s. Text).Farblose würfelförmige Einkristalle von bislang unbekanntem CsK4[GaO4] entstehen aus K2O, CsGaO2 und Cs2O (überschuß) im zugeschweißten Au-Rohr bei 580°C. RGr. Pbca mit a = 1154,7, b = 667,7, c = 2096,6 pm, Z = 8 [Vierkreisdiffraktometerdaten, 1798 I0(hkl), MoKα, R = 7,62%, Rw = 7,68%, anisotrope Verfeinerung] (Parameter s. Text). Beide Kristallstrukturen gehören zum Na5[GaO4]-Typ. Strukturelle Aspekte, ECoN und MAPLE von KNa4[GaO4] und CsK4[GaO4] werden im Vergleich zu Na5[GaO4] diskutiert.

    Description / Table of Contents: The First Oxide with the Formula Type K5[MO4]: K5[TlO4]Light yellow powder and pale yellow transparent single crystals of K5[TlO4] were newly prepared from mixtures of binary oxides (K2O/Tl2O3) preheated and levigated several times [closed Ag-cylinder, 580°C, 24 h and 600°C, 20 d]. Space group Pbca with a = 1170.4(3), b = 686.1(1), c = 2079.2(5) pm, Z = 8 [four-circle-diffraktometer data, 997 I0(hkl), R = 7.87%, Rw = 5.63%, MoKα] (parameter s. text). The crystal structure belongs to the Na5[GaO4] type. Structural aspects, ECoN and MAPLE are discussed.
    Notes: Neu dargestellt wurden hellgelbes Pulver und blaßgelbe durchsichtige Einkristalle von K5[TIO4] aus mehrmals innig verriebenen, vorgetemperten Gemengen der binären Oxide (K2O/Tl2O3) [geschlossenes Ag-Bömbchen, 580°C, 24 h bzw. bei 600°C, 20 d]. Es liegt die Raumgruppe Pbca mit a = 1170,4(3), b = 686,1(1), c = 2079,2(5) pm, Z = 8 vor. [Vierkreisdiffraktometerdaten, 997 I0(hkl), R = 7,87%, Rw = 5,63%, MoKα] (Parameter s. Text). K5[TlO4] ist isotyp zu Na5[GaO4]. Strukturelle Aspekte, ECoN und MAPLE werden diskutiert.
