    Description / Table of Contents: Enehydrazines, 131) Some Products from Methyl 3-Hydroxy-1-methyl-5-pyrazolecarboxylate and 1-Benzyl-3-hydroxypyrazoleSome esters and ethers of the 3-pyrazolones 1a, 2c and6a are Prepared. They are derived from the tautomeric 3-hydroxypyrazole forms in which the free starting compounds mostly occur. Some substitutions in 4-position are likewise described.
    Notes: Es werden einige Ester und Äther der 3-Pyrazolone 1a, 2c und 6a dargestellt, die sich von der tautomeren 3-Hydroxypyrazol-Form herleiten, in der auch die freien Ausgangsverbindungen vorliegen. Einige Substitutionen in 4-Stellung der 3-Hydroxypyrazole werden ebenfalls beschrieben.

    Description / Table of Contents: Thermal Behaviour of Li3MnO4. II. α- and β-Li2MnO3By thermal decomposition of Li3MnO4 we obtained two new forms of Li2MnO3: α-Li2MnO3 crystallizes due to Guinier-Simon photographs cubic face-centered with a = 4.092 Å, β-Li2MnO3 hexagonal with a = 4,93, c = 14.24 Å, c/a = 2.89. α-Li2MnO3 is paramagnetic with μ = 3,82 B.M. Below the Neel temperature (≈ 50 K) β-Li2MnO3 is antiferromagnetic. Effective Coordination Numbers, ECoN, are calculated and discussed.
    Notes: Durch thermische Zersetzung von Li3MnO4 wurden zwei neue Formen von Li2MnO3 erhalten: Nach Guinier-Simon-Aufnahmen kristallisiert α-Li2MnO3 kubisch-flächenzentriert mit a = 4,092 Å, β-Li2MnO3 hexagonal mit a = 4,93, c = 14,24 Å, c/a = 2,89. α-Li2MnO3 ist paramagnetisch mit μ = 3,82 B.M., β-Li2MnO3 ist unterhalb der NEEL-Temperatur von ≈ 50 K antiferromagnetisch. Effektive Koordinationszahlen, ECoN, werden berechnet und diskutiert.

    Description / Table of Contents: Thermal Behaviour of Li3MnO4. I. α- and β-Li3MnO4Li3MnO4 exists, due to Guinier-Simon photographs in two forms: α-Li3MnO4 (sky-blue) is isotypic with LT-Li3VO4, β-Li3MnO4 with HT-Li3PO4 (lattice constants and parameters see text). Both forms show paramagnetic behaviour with μ = 2.68 resp. 2.77 B.M. (θ≈ 0 K). The Madelung Part of Lattice Energy, MAPLE, and Effective Coordination Numbers, ECoN, are calculated and discussed.
    Notes: Li3MnO4 tritt nach Guinier-Simon-Aufnahmen in zwei Formen auf: α-Li3MnO4 (himmelblau) ist isotyp mit LT-Li3VO4, β-Li3MnO4 (flaschengrün) mit HT-Li3PO4 (Gitterkonstanten und Parameter siehe Text). Beide Formen sind paramagnetisch mit μ = 2,68 bzw. 2,77 B.M. (θ jeweils 0 K). Der Madelunganteil der Gitterenergie, MAPLE, und Effektive Koordinationszahlen, ECoN, werden berechnet und diskutiert.

    Description / Table of Contents: The Crystal Structure of CsTcO4CsTcO4 crystallizes orthorhombic with a = 5.727, b = 5.921 and c = 14.34 Å. Z = 4, space group Pnma (Nr. 62, I.T.). The metal positions were refined by single crystal data, the oxygen positions first determined: the CsTcO4 structure is a slight distortion of the scheelite arrangement (parameters: see text). The MADELUNG Part of Lattice Energy, MAPLE, „Mean Effective Ionic Radii“, MEIR, and Effective Coordination Numbers, ECoN, are calculated and discussed.
    Notes: CsTcO4 kristallisiert orthorhombisch mit a = 5,727, b = 5,921 und c = 14,34 Å, Z = 4, in der Raumgruppe Pnma (Nr. 62, I.T.). Die Lageparameter von Cs und Tc wurden aus Einkristalldaten verfeinert, die O-Positionen erstmals bestimmt (Parameter: vgl. Text). Es liegt eine Verzerrungsvariante des Scheelittyps vor. Der MADELUNG-Anteil der Gitterenergie, MAPLE, sowie „Mittlere Effektive Ionenradien“, MEIR, und Effektive Koordinationszahlen, ECoN, werden berechnet und diskutiert.
