Crystal structure of an oxygen deficient strontium cobaltate, Sr_6Co_5O_<14.3>
スポンサーリンク
概要
- 論文の詳細を見る
The crystal structure of Sr_6Co_5O_<14.3> has been analyzed by X-ray diffraction of a c-axis elongated prismatic single crystal grown by a flux method. Sr_6Co_5O_<14.3> is an oxygen deficient phase of Sr_6Co_5O_<15> that contains one-dimensional columns of Co-O octahedra and triangular prisms. Oxygen defects are preferentially introduced in an O site shared by the Co-O triangular prism and octahedron in the structure of Sr_6Co_5O_<15>. The average structure of Sr_6Co_5O_<14.3> is refined by splitting the oxygen defect site with the rhombohedral space group R3 (a=9.4334(6) Å and c=12.5156(6)Å).
