Abstract

The crystal structure of Sr₆Co₅O_14.3 has been analyzed by X-ray diffraction of a c-axis elongated prismatic single crystal grown by a flux method. Sr₆Co₅O_14.3 is an oxygen deficient phase of Sr₆Co₅O₁₅ 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 Sr₆Co ₅O₁₅. The average structure of Sr₆Co ₅O_14.3 is refined by splitting the oxygen defect site with the rhombohedral space group R3 (a = 9.4334(6) Åand c = 12.5156(6)Å).
