Synthesis and Structural Characterization of Two New Hexagonal Osmates: Ba2Fe0.92Os1.08O6 and Ba2Co0.77Os1.23O6
Two complex oxides of osmium, Ba2Fe0.92Os1.08O6 and Ba2Co0.77Os1.23O6, have been prepared as single crystals from molten potassium hydroxide. Both oxides crystallize in the hexagonal space group P63mc with a = 5.7403(1) Å and c = 14.0771(6) Å and a = 5.7745(2) Å and c = 14.0946(7) Å for Ba2Fe0.92Os1.08O6 and Ba2Co0.77Os1.23O6, respectively. The structure of these compounds is related to the 6H–BaTiO3 structure but exhibit mixed occupancy of both metals on the three crystallographically independent metal sites.
