a Experimentally obtained XRD patterns are presented for BaIrO3 and Ba2(MnIr)O6. b, c In addition to the experimental patterns, XRD simulations are provided to support chemical ordering in the 6H and 12R polytypes. d–f Atomic-scale HAADF images are demonstrated for all seven iridates, showing the Z-contrast features. Yellow circles in each image denote the Ir columns. White arrows indicate the ordered configurations by dopants.
