Ca sub (1-x) CuO sub 2, a NaCuO sub 2 -type related structure.
01 January 1990
The crystal structure of Ca sub (1-x) CuO sub 2, a low temperature phase in the Ca-Cu-O system, has been studied by X-ray diffraction. The structure contains edge shared chains of CuO sub 4 squares, forming linear [CuO sub 2]-chains and is related to the NaCuO- type. In contrast to the NaCuO sub 2 -type, the calcium atoms are not well localized and various superstructures due to different Ca ordering are observed.
