Materials Data on RbAsF6 by Materials Project

RbAsF6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Rb1+ is bonded to twelve equivalent F1- atoms to form RbF12 cuboctahedra that share corners with six equivalent AsF6 octahedra, edges with six equivalent RbF12 cuboctahedra, and faces with two equivalent AsF6 octahedra. The corner-sharing octahedral tilt angles are 33°. There are six shorter (3.06 Å) and six longer (3.17 Å) Rb–F bond lengths. As5+ is bonded to six equivalent F1- atoms to form AsF6 octahedra that share corners with six equivalent RbF12 cuboctahedra and faces with two equivalent RbF12 cuboctahedra. All As–F bond lengths are 1.78 Å. F1- is bonded in a single-bond geometry to two equivalent Rb1+ and one As5+ atom.
