Materials Data on K2RbScF6 by Materials Project
RbK2ScF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Rb1+ is bonded to six equivalent F1- atoms to form RbF6 octahedra that share corners with six equivalent ScF6 octahedra and faces with eight equivalent KF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Rb–F bond lengths are 2.64 Å. K1+ is bonded to twelve equivalent F1- atoms to form KF12 cuboctahedra that share corners with twelve equivalent KF12 cuboctahedra, faces with six equivalent KF12 cuboctahedra, faces with four equivalent RbF6 octahedra, and faces with four equivalent ScF6 octahedra. All K–F bond lengths are 3.32 Å. Sc3+ is bonded to six equivalent F1- atoms to form ScF6 octahedra that share corners with six equivalent RbF6 octahedra and faces with eight equivalent KF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Sc–F bond lengths are 2.03 Å. F1- is bonded in a distorted linear geometry to one Rb1+, four equivalent K1+, and one Sc3+ atom.
