Materials Data on RbIrO3 by Materials Project

Abstract

RbIrO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Rb1+ is bonded to twelve equivalent O2- atoms to form RbO12 cuboctahedra that share corners with twelve equivalent RbO12 cuboctahedra, faces with six equivalent RbO12 cuboctahedra, and faces with eight equivalent IrO6 octahedra. All Rb–O bond lengths are 2.83 Å. Ir5+ is bonded to six equivalent O2- atoms to form IrO6 octahedra that share corners with six equivalent IrO6 octahedra and faces with eight equivalent RbO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ir–O bond lengths are 2.00 Å. O2- is bonded to four equivalent Rb1+ and two equivalent Ir5+ atoms to form a mixture of distorted edge, corner, and face-sharing ORb4Ir2 octahedra. The corner-sharing octahedra tilt angles range from 0–60°.
