Materials Data on RbCrO3 by Materials Project
RbCrO3 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 CrO6 octahedra. All Rb–O bond lengths are 2.79 Å. Cr5+ is bonded to six equivalent O2- atoms to form CrO6 octahedra that share corners with six equivalent CrO6 octahedra and faces with eight equivalent RbO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Cr–O bond lengths are 1.97 Å. O2- is bonded in a distorted linear geometry to four equivalent Rb1+ and two equivalent Cr5+ atoms.
