Rietveld refinements using powder diffraction data indicate that all the compounds crystallize in the 6H-BaTiO3 structure type in space group P63/mmc. Magnetic susceptibility measurements were carried out on each compound. Effective magnetic moments were smaller than values estimated using spin-only moments, which indicate the presence of spin-orbit coupling and strong interactions in the [(Ru0.5Ir0.5)2O9] face-sharing octahedra that contain a disordered mixture of Ru and Ir on a single crystallographic site. Magnetic anomalies were observed for the compounds Ba3PrRuIrO9, Ba3TbRuIrO9, and Ba3NdRuIrO9 at 3.5, 13, and 8 K, respectively.

Near 4 GPa, the oxide undergoes a pressure-induced phase transition. The symmetry of the material changes during the phase transition from space group R3¯ to space group I2/m, which is consistent with a change in the octahedral tilting distortion from an a-a-a- type to a0b-b- type using the Glazer notation. A fit of the volume pressure data using the Birch Murnagaham equation of state yielded a bulk modulus of 144(8) GPa for the rhombohedral phase.
