摘要: Abstract A body-centered cubic structure related to the KSbO 3 strcture has been found for phases with compositions close Ba 0.5 IrO , Sr OsO and ReO . primitive also NaOsO BiPtO 3.5 BiOsO The ternary oxides Cd 2 Ir O 7 Ca 1.7 Os have prepared pyrochlore structure. All iridium contain 5+ are first oxide examples of in an oxidation state higher than four.
