Abstract

Two complex oxides of osmium, Ba₂Fe_0.92Os_1.08O₆ and Ba₂Co_0.77Os_1.23O₆, 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 Ba₂Fe_0.92Os_1.08O₆ and Ba₂Co_0.77Os_1.23O₆, 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.
