Cs2CoF6 crystallizes in the trigonal R-3m space group. Cs(1) is bonded to twelve equivalent F(1) atoms to form distorted CsF12 cuboctahedra that share corners with twelve equivalent Cs(1)F12 cuboctahedra, faces with six equivalent Cs(1)F12 cuboctahedra, and faces with four equivalent Co(1)F6 octahedra. Co(1) is bonded to six equivalent F(1) atoms to form CoF6 octahedra that share faces with eight equivalent Cs(1)F12 cuboctahedra. F(1) is bonded in a single-bond geometry to four equivalent Cs(1) and one Co(1) atom.
Cs2CoF6 crystallizes in the trigonal R-3m space group. Cs(1) is bonded to twelve equivalent F(1) atoms to form distorted CsF12 cuboctahedra that share corners with twelve equivalent Cs(1)F12 cuboctahedra, faces with six equivalent Cs(1)F12 cuboctahedra, and faces with four equivalent Co(1)F6 octahedra. There are three shorter (3.15 Å) and nine longer (3.16 Å) Cs(1)-F(1) bond lengths. Co(1) is bonded to six equivalent F(1) atoms to form CoF6 octahedra that share faces with eight equivalent Cs(1)F12 cuboctahedra. All Co(1)-F(1) bond lengths are 1.80 Å. F(1) is bonded in a single-bond geometry to four equivalent Cs(1) and one Co(1) atom.
