Materials Data on Rb3BrO by Materials Project
Rb3OBr is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Rb1+ is bonded in a distorted linear geometry to two equivalent O2- and four equivalent Br1- atoms. Both Rb–O bond lengths are 2.79 Å. All Rb–Br bond lengths are 3.94 Å. O2- is bonded to six equivalent Rb1+ atoms to form ORb6 octahedra that share corners with six equivalent ORb6 octahedra and faces with eight equivalent BrRb12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. Br1- is bonded to twelve equivalent Rb1+ atoms to form BrRb12 cuboctahedra that share corners with twelve equivalent BrRb12 cuboctahedra, faces with six equivalent BrRb12 cuboctahedra, and faces with eight equivalent ORb6 octahedra.
