An Oxoindate/zincatesol;zincate with Zn10O20 and In4O16 Macropolyhedra with Zn2+ in Tetrahedral Coordination by O2-Ba3In2Zn5O11 was prepared for the first time by a flux technique and investigated by single crystal X-ray work. It crystallizes with cubic symmetry, space group T2d-F43m, a = 13.3588 Å, Z = 8. Zn2+ show tetrahedral coordination by O2-, forming Zn10O20 macropolyhedra. In addition the nZn/Osol;O part of the crystal structure is made up of Zn10O20 parts. Edge connection of four InO6 octahedra results in In4O16 groups. The crystal structure will be shown and discussed.

    Description / Table of Contents: On the Crystal Chemistry of a New Barium Rare-Earth Oxozincate: Ba2Er2Zn8O13High temperature reactions led to single crystals of Ba2Er2Zn8O13. It crystallizes with orthorhombic symmetry, space group C122v—Cmc21, a = 6.276, b = 10.871, c = 10.195 Å, Z = 2. The hitherto unknown crystal structure shows Zn2+ with tetrahedral, Er3+ octahedral and Ba2+ cuboctahedral coordination by O2-. It will be shown that parts of the [Zn8O13] network are fragments of the ZnO structure showing O2- within a tetrahedral zinc coordination. A deficit of two O2- ions per unit cell is focused on two point positions.
    Notes: Durch Hochtemperaturreaktionen wurden Einkristalle von Ba2Er2Zn8O13 dargestellt und anschließend röntgenographisch untersucht. Die Verbindung kristallisiert in einem neuen Strukturtyp mit orthorhombischer Symmetrie, Raumgruppe C122v—Cmc21; a = 6,276; b = 10,871; c = 10,195 Å; Z = 2. Die bisher unbekannte Kristallstruktur zeigt Zn2+ in tetraedrischer, Er3+ in oktaedrischer und Ba2+ in kuboktaedrischer Koordination von O2-. Es wird gezeigt, daß das [Zn8O13]-Gerüst Fragmente der ZnO-Struktur mit O2- in tetraedrischer Zinkkoordination enthält. Ein Defizit von zwei O2 pro Elementarzelle verteilt sich auf zwei Punktlagen.

    Description / Table of Contents: A new Alkaline-Earth Platinum Copper Oxide: Ca3.5Cu0.5PtO6Ca3.5Cu0.5PtO6 was prepared and investigated by single crystal X-ray work. (Space group C23—C12/m1; a = 9.0743; b = 9.2527; c = 6.4840 Å; β = 91.448°; Z = 4). The crystal structure of the previously unknown compound is closely related to the structure of Sr3PtCuO6 and Sr3IrCuO6 as well as the rhombohedral phases M4PtO6 (M = Ba, Sr, Ca). Typical features of the crystal chemistry are isolated chains of PtO6 octahedra, alternately allyed by square CuO4 polygones and trigonal prisms of O2- around Ca2+.
    Notes: Ca3,5Cu0,5PtO6 wurde dargestellt und an Einkristallen mit Röntgenmethoden untersucht. (Raumgruppe C23—C12/m1 a = 9,0743; b = 9,2527; c = 6,4840 Å; β = 91,448°; Z = 4). Diese bisher unbekannte Substanz bildet einen Strukturtyp, der eng mit Sr3CuPtO6 und Sr3CuIrO6 bzw. mit den rhomboedrischen Phasen M4PtO6 (M = Ba, Sr, Ca) verwandt ist. Charakteristische Bauelemente sind isolierte Ketten, welche aus PtO6-Oktaedern aufgebaut sind, die abwechselnd durch quadratische CuO4-Polygone und trigonale Prismen um Ca2+ miteinander verbunden werden.
