# BaIrO_{3}

BaIrO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Ba(1) is bonded to twelve equivalent O(1) atoms to form BaO12 cuboctahedra that share corners with twelve equivalent Ba(1)O12 cuboctahedra, faces with six equivalent Ba(1)O12 cuboctahedra, and faces with eight equivalent Ir(1)O6 octahedra. All Ba(1)–O(1) bond lengths are 2.88 Å. Ir(1) is bonded to six equivalent O(1) atoms to form IrO6 octahedra that share corners with six equivalent Ir(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. All Ir(1)–O(1) bond lengths are 2.04 Å. O(1) is bonded to four equivalent Ba(1) and two equivalent Ir(1) atoms to form a mixture of distorted face, edge, and corner-sharing OBa4Ir2 octahedra. The corner-sharing octahedral tilt angles range from 0–60°.
