    Description / Table of Contents: Oxidation of Intermetallic Phases: K4{Na2[Tl2O6]} from NaTl and K2O2The hitherto unknown K4{Na2[Tl2O6]} was prepared in form of transparent, yellow single crystals from NaTl and KO1,08 (molar ratio 1:1.3; sealed Ag-cylinder; 450°C, 30 d). The structure determination (four-circle diffractometer, MoKα, 1 280 out of 1 523 Io(hkl), R = 5.75%, Rw = 4.58%) confirms the space group P21/c with a = 641.3 pm, b = 691.1 pm, c = 1188.5 pm, β = 95.69° and Z = 2. As characteristic building units of the structure there are doubles of tetrahedra of [Tl2O6] and [Na2O6]. The compound is isotypic with Cs6[In2O6] and Rb6[Tl2O6]. The Madelung Part of Lattice Energy, MAPLE, the Mean Fictive Ionic Radii, MEFIR, Effective Coordination Numbers, ECoN, and Charge Distribution, CHARDI, are calculated.
    Notes: Bisher unbekanntes K4{Na2[Tl2O6]} wurde durch Oxydation von NaTl mit KO1,08 (1:1,3; geschlossener Ag-Zylinder; 450°C; 30 Tage) in Form transparenter, gelber Einkristalle dargestellt. Die Strukturaufklärung (Vierkreisdiffraktometerdaten, MoKα, 1 280 von 1 523 Io(hkl), R = 5,75%, Rw = 4,58%) erfolgte in der Raumgruppe P21/c mit a = 641,3 pm, b = 691,1 pm, c = 1 188,5 pm, β = 95,69° und Z = 2. Charakteristisches Motiv sind über Kanten verknüpfte, von ihresgleichen „isolierte“ Tetraederdoppel [Tl2O6] und [Na2O6]. Die Verbindung ist isotyp zu Cs6[In2O6] und Rb6[Tl2O6]. Der Madelunganteil der Gitterenergie, MAPLE, die Mittleren fiktiven Ionenradien, MEFIR, Effektive Koordinationszahlen, ECoN, sowie die Ladungsverteilung, CHARDI, werden berechnet.

    Description / Table of Contents: The First Basic Oxoindate: Na26O3[InO4]4For the first time Na26O3[InO4]4 was obtained by annealing intimate mixtures of Na2O, CdO and elemental In (molar ratio 3.5:1.0:2.0) in closed Ni-cylinders (30 days, 600°C) in form of yellow single crystals. The structure determination by four circle diffractometer data (MoKα, 921 out of 921 Io(hkl), R = 2.53, Rw = 2.18%) confirms the space group 143d (cubic) with a = 1 427.37 pm and Z = 4. All kation are surrounded by tetrahedron of O2-. In3+ is coordinated with O(1) and O(2) (without O(3)) only. There are „isolated“ [InO4]-tetrahedra. The Madelung Part of Lattice Energy, MAPLE, the Mean Fictive Ionic Radii, MEFIR, Effective Coordination Numbers, ECoN, and Charge Distribution, CHARDI, are calculated.
    Notes: Beim Tempern inniger Gemenge von Na2O, CdO und elementarem In (3,5:1,0:2,0) in verschlossenen Ni-Zylindern (30 Tage, 600°C) erhielten wir gelbe Einkristalle von Na26O3[InO4]4. Die Strukturaufklärung (Vierkreisdiffraktometerdaten, MoKα, 921 von 921 Io(hkl), R = 2,53, Rw = 2,18%) erfolgte in der Raumgruppe 143d (kubisch) mit a = 1 427,37 pm und Z = 4. Alle Kationen sind tetraedrisch von O2- umgeben; In3+ jedoch nur von O(1) und O(2) und nicht von O(3). Strukturcharakteristisch sind die „Inseln“ [InO4], auffallend die C.N. 8 für O(3). Der Madelunganteil der Gitterenergie, MAPLE, die Mittleren Fiktiven Ionenradien, MEFIR, Effektive Koordinationszahlen, ECoN, sowie die Ladungsverteilung, CHARDI, werden berechnet.

    Description / Table of Contents: The First Oxothallate(III) with the Formula Type AA4′[MO4]: CsK4[TlO4]For the first time CsK4[TlO4] was obtained by heating intimate mixtures of K2O, CdO and CsTl (molar ratio 3.1:1.0:1.0) in closed Ag-cylinders (25 days, 450°C) in form of yellow, transparent single crystals. The structure determination by four circle diffractometer data (MoKα, 1922 out of 2 094 Io(hkl), R = 2.98, Rw = 2.49) confirms the space group Pbca with lattice constants a = 1 192.1 pm; b = 685.7 pm; c = 2 143.5 pm; Z = 8. The structure is isotypic with Na5[GaO4]. The Madelung Part of Lattice Energy, MAPLE, the Mean Fictive Ionic Radii, MEFIR, Effective Coordination Numbers, ECoN, and Charge Distribution, CHARDI, are calculated.

    Description / Table of Contents: The First Oligooxoindate(III): K14[In4O13]For the first time K14[In4O13] was obtained by heating intimate mixtures of K2O, CdO and elementar In (molar ratio 3.1:1.0:1.0) in closed Ag-cylinders (30 days, 450°C) in form of yellow-brown single crystals. The structure determination by four circle diffractometer data MoKα, 3 689 out of 3 689 Io(hkl), R = 4.22, Rw = 2.45) confirms the space group P21/c with lattice constants a = 687.7 pm; b = 3 118.5 pm; c = 686.4 pm; β = 119.3°; Z = 2. The characteristic feature of the structure is [In4O13]14- groups, oligomers consisting of four corner-sharing InO4 tetrahedra. These groups are connected by crystallographically distinct potassium atoms. The structure is isotypic with Na14[Al4O13] [2] and K14[Fe3O13] [3]. ECoN and MAPLE calculationes are discussed.
    Notes: Beim Tempern inniger Gemenge von K2O, CdO und elementarem In (Einwaageverhältnis 3,1:1,0:1,0) in verschlossenen Ag-Zylindern (30 Tage, 450°C) erhielten wir neben schwach roten Kristallen von K5InO4 [1] auch gelbbraune Kristalle von K14[In4O13]. Die Strukturaufklärung (Vierkreisdiffraktometerdaten, MoKα, 3 698 von 3 698 Io(hkl), R = 4,22%, Rw = 2,45%) erfolgte in der Raumgruppe P21/c mit den Gitterkonstanten: a = 687,7 pm; b = 3 118,5 pm; c = 686,4 pm; β = 119,3°; Z = 2. Charakteristischer Teil der Struktur sind „isolierte“ Baugruppen [In4O13]14-, die aus vier über Ecken verknüpften InO4-Tetraedern bestehen und durch kristallographisch unterschiedliche K+ in verschiedenen Richtungen verknüpft werden. Dieses Oxid ist isotyp zu Na14[Al4O13] [2] und K14[Fe4O13] [3]. Der Madelunganteil der Gitterenergie MAPLE wird berechnet und mit den binären Oxiden verglichen.

    Description / Table of Contents: A New „Orthoindate“ of an Alkali Metal: K5[InO4]Hitherto unknown K5[InO4] was prepared by heating intimate mixtures of K2O, In2O3 and elementar In (molar ratio 10.0 : 1.0 : 4.0) in closed Ni-cylinders (30 days, 500°C) in form of pale red, nearly colourless, transparent, single crystals. Same crystals were obtained by heating mixtures of K2O, CdO and elementar In (molar ratio 3.1 : 1.0 : 1.0) in closed Ag-cylinders (30 days, 450°C), too. In this case we also found yellow-brown crystals of K14[In4O13] [1]. Structure determination by four circle diffractometer data (MoKα, 15279 out 17454 Io(hkl), R = 5.60%, Rw = 5.25%). Space group P1 with a = 1827.9 pm; b = 1694.4 pm; c = 1329.4 pm; α = 113.3°; β = 111.4°; γ = 105.2°; Z = 16. Characteristic feature of the structure are isolated [InO4]5--tetraeder. The Madelung Part of Lattice Energy, MAPLE, the Mean Fictive Ionic Radii, MEFIR, Effective Coordination Numbers, ECoN, and Charge Distribution, VADI, are calculated.
    Notes: Beim Tempern inniger Gemenge von K2O, In2O3 und elementarem In (10,0 : 1,0 : 4,0) in verschlossenen Ni-Zylindern (30 Tage, 500°C) erhielten wir erstmals K5[InO4] als blaßrote, fast farblose, transparente Einkristalle. Gleichartige Kristalle erhielten wir auch beim Tempern von K2O, CdO und elementarem In (3,1 : 1,0 : 1,0) in verschlossenen Ag-Zylindern (30 Tage, 450°C). Neben den blaßroten Kristallen von K5[InO4] lagen in dieser Probe auch bernsteinfarbene Kristalle von ebenfalls vorher unbekanntem K14[In4O13] [1] vor. Die Strukaufklärung (Vierkreisdiffraktometerdaten, MoKα, 15279 von 17454 Io(hkl), R = 5,60%, Rw = 5,25%) erfolgte in der Raumgruppe P1 mit den Gitterkonstanten: a = 1827,9 pm; b = 1694,4 pm; c = 1329,4 pm; α = 113,28°; β = 111,39°; γ = 105,20°; Z = 16. Für die Struktur sind „isolierte“ [InO4]5--Tetraeder charakteristisch. Der Madelunganteil der Gitterenergie, MAPLE, die mittleren fiktiven Ionenradien, MEFIR, Effektive Koordinationszahlen, ECoN, sowie die Ladungsverteilung werden berechnet.
