Description
The compounds Ba3SmRu2O9, Ba3SmIrRuO9, and Ba2InIrO6 have a hexagonal BaTiO3 structure (sequence (hcc)2) with an ordered cationic distribution. The 6 L stacking polytypes Ba3BM2O9 show an 1:2 order (M2O9 double octahedra and BO6 single groups) and crystallize in the space group P63/mmc. The refined, intensity related R' values are 6.9% (Ba3SmRu2O9) and 6.5% (Ba3SmIrRuO9). The 1:1 ordered Ba2InIrO6, with InIrO9 double groups and InO6-, IrO6-single octahedra, belongs to the space group P-3m1; the refined R' is 7.3%. (author)
