    Description / Table of Contents: By slowly oxydation of NaTl, a new cubic form of NaTlO2 has been obtained: a=4.76 Å, dx=7.99 and dpyk=7.98 g · cm-3, NaCl type of structure, 2 formula units/unit cell, with random distribution of the cations. At 500°C it transforms to the known hexagonal form of NaTlO2, and annealing (700—750°C) for 6 days yields single crystals of the latter form, the crystal structure of which has been refined by means of FOURIER methods.
    Notes: Durch langsame Oxydation von NaTl wird eine neue, kubische Form von NaTlO2 erhalten: a=4,76 Å, drö=7,99 und dpyk=7,98 g · cm-3, NaCl-Typ mit statistischer Verteilung der Kationen, 2 Formeleinheiten/Elementarzelle. Diese wandelt sich bei 500°C in die bekannte hexagonale Form um und liefert bei sechstägigem Tempern (700—750°C) im verschlossenen Ag-Bömbchen Einkristalle der zweiten Form. Mit Hilfe von FOURIERmethoden wurde deren Kristallstruktur verfeinert.
