Materials Data on RbAuF3 by Materials Project
RbAuF3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Rb1+ is bonded to twelve equivalent F1- atoms to form RbF12 cuboctahedra that share corners with twelve equivalent RbF12 cuboctahedra, faces with six equivalent RbF12 cuboctahedra, and faces with eight equivalent AuF6 octahedra. All Rb–F bond lengths are 3.19 Å. Au2+ is bonded to six equivalent F1- atoms to form AuF6 octahedra that share corners with six equivalent AuF6 octahedra and faces with eight equivalent RbF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Au–F bond lengths are 2.26 Å. F1- is bonded to four equivalent Rb1+ and two equivalent Au2+ atoms to form a mixture of distorted face, edge, and corner-sharing FRb4Au2 octahedra. The corner-sharing octahedra tilt angles range from 0–60°.
