Materials Data on RbMnF3 by Materials Project
RbMnF3 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 MnF6 octahedra. All Rb–F bond lengths are 3.05 Å. Mn2+ is bonded to six equivalent F1- atoms to form MnF6 octahedra that share corners with six equivalent MnF6 octahedra and faces with eight equivalent RbF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Mn–F bond lengths are 2.16 Å. F1- is bonded in a distorted linear geometry to four equivalent Rb1+ and two equivalent Mn2+ atoms.
