CsRuF6 crystallizes in the trigonal R-3m space group. Cs(1) is bonded to twelve equivalent F(1) atoms to form CsF12 cuboctahedra that share corners with six equivalent Ru(1)F6 octahedra, edges with six equivalent Cs(1)F12 cuboctahedra, and faces with two equivalent Ru(1)F6 octahedra. The corner-sharing octahedral tilt angles are 32°. Ru(1) is bonded to six equivalent F(1) atoms to form RuF6 octahedra that share corners with six equivalent Cs(1)F12 cuboctahedra and faces with two equivalent Cs(1)F12 cuboctahedra. F(1) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one Ru(1) atom.

The corner-sharing octahedral tilt angles are 32°. There are six shorter (3.09 Å) and six longer (3.24 Å) Cs(1)-F(1) bond lengths. Ru(1) is bonded to six equivalent F(1) atoms to form RuF6 octahedra that share corners with six equivalent Cs(1)F12 cuboctahedra and faces with two equivalent Cs(1)F12 cuboctahedra. All Ru(1)-F(1) bond lengths are 1.87 Å. F(1) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one Ru(1) atom.
