In the thirtieth O2- site, O2- is bonded to four Ba2+ and two Ir4+ atoms to form distorted OBa4Ir2 octahedra that share corners with three OBa4Ir2 octahedra, corners with two equivalent OBa4Ir square pyramids, an edgeedge with one OBa4Ir2 octahedra, and a faceface with one OBa4Ir2 octahedra. The corner-sharing octahedra tilt angles range from 33–58°. In the thirty-first O2- site, O2- is bonded in a 6-coordinate geometry to four Ba2+ and two Ir4+ atoms. In the thirty-second O2- site, O2- is bonded to four Ba2+ and two Ir4+ atoms to form a mixture of distorted corner, edge, and face-sharing OBa4Ir2 octahedra. The corner-sharing octahedra tilt angles range from 35–56°. In the thirty-third O2- site, O2- is bonded to four Ba2+ and two Ir4+ atoms to form distorted OBa4Ir2 octahedra that share corners with two OBa4Ir2 octahedra, an edgeedge with one OBa4Ir2 octahedra, an edgeedge with one OBa4Ir square pyramid, faces with two OBa4Ir2 octahedra, and a faceface with one OBa4Ir square pyramid. The corner-sharing octahedra tilt angles range from 28–57°. In the thirty-fourth O2- site, O2- is bonded to four Ba2+ and two Ir4+ atoms to form distorted OBa4Ir2 octahedra that share c},
