title: Ca(4)IrO(6), Ca(3)MgIrO(6) and Ca(3)ZnIrO(6).
abstract: Single crystals of tetracalcium iridium hexaoxide, Ca(4)IrO(6), tricalcium magnesium iridium hexaoxide, Ca(3)MgIrO(6), and tricalcium zinc iridium hexaoxide, Ca(3)ZnIrO(6), were prepared via high-temperature flux growth and structurally characterized by single-crystal X-ray diffraction. The three compounds are isostructural and adopt the K(4)CdCl(6) structure type, comprised of chains of alternating face-shared [CaO(6)], [MgO(6)] or [ZnO(6)] trigonal prisms and [IrO(6)] octahedra, surrounded by columns of Ca(2+) ions.
