Synthesis and selective topochemical fluorination of the cation and anion-vacancy ordered phases Ba2YCoO5 and Ba3YCo2O7.5.

The synthesis and characterization of two cation-ordered, anion-vacancy ordered phases, Ba2YCoO5 and Ba3YCo2O7.5, is described. Neutron powder diffraction data reveal both phases adopt structures in which octahedral Y(3+) and tetrahedral Co(3+) centers are ordered within a "cubic" perovski...
