    Description / Table of Contents: SrCu0.75Ni0.25O2 was prepared and its crystal structure explained by x-ray diffraction dates (a = 3.565, b = 16.308 and c = 3.916 Å, space group D2h17—Cmcm). The structure of this compound is determined by the connection of trigonal prisms around Sr2+ which is characteristic for earth-alkaline oxocuprates, and square plane configurations of O2- around Cu2+. The lattice is penetrated by double ribbons of connected squares. The structure of SrCu0.75Ni0.25O2 stands between those of CaCu2O3 and Sr2CuO3.
    Notes: Die Verbindung SrCu0,75Ni0,25O2 wurde dargestellt und an Einkristall-Röntgenbeugungsdaten die Kristallstruktur aufgeklärt (a = 3,565, b = 16,308 und c = 3,916 Å, Raumgruppe D2h17—Cmem). Die für Erdalkalimetalloxocuprate charakteristische Verknüpfung trigonaler Prismen um Sr2+ und quadratisch ebene Konfigurationen von O2- um Cu2+ bestimmen auch den Aufbau dieser Verbindung. Das Kristallgitter wird von Doppelbändern ebener, über je zwei gemeinsame Kanten verknüpfter „Sauerstoffvierecke“ durchzogen. SrCu0,75Ni0,25O2 ist strukturell zwischen CaCu2O3 und Sr2CuO3 einzuordnen.
