Abstract: | A new Alkaline-Earth Platinum Copper Oxide: Ca3.5Cu0.5PtO6 Ca3.5Cu0.5PtO6 was prepared and investigated by single crystal X-ray work. (Space group C ? 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+. |
