Materials Data on RbRuF6 by Materials Project
RbRuF6 crystallizes in the trigonal R-3m 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 RuF6 octahedra, edges with six equivalent RbF12 cuboctahedra, and faces with two equivalent RuF6 octahedra. The corner-sharing octahedral tilt angles are 33°. There are six shorter (3.04 Å) and six longer (3.19 Å) Rb–F bond lengths. Ru5+ is bonded to six equivalent F1- atoms to form RuF6 octahedra that share corners with six equivalent RbF12 cuboctahedra and faces with two equivalent RbF12 cuboctahedra. All Ru–F bond lengths are 1.90 Å. F1- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one Ru5+ atom.
