Materials Data on RbFeO3 by Materials Project
RbFeO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Rb is bonded to twelve equivalent O atoms to form RbO12 cuboctahedra that share corners with twelve equivalent RbO12 cuboctahedra, faces with six equivalent RbO12 cuboctahedra, and faces with eight equivalent FeO6 octahedra. All Rb–O bond lengths are 2.86 Å. Fe is bonded to six equivalent O atoms to form FeO6 octahedra that share corners with six equivalent FeO6 octahedra and faces with eight equivalent RbO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Fe–O bond lengths are 2.02 Å. O is bonded to four equivalent Rb and two equivalent Fe atoms to form a mixture of distorted edge, corner, and face-sharing ORb4Fe2 octahedra. The corner-sharing octahedra tilt angles range from 0–60°.
