Materials Data on Tl2VF6 by Materials Project
VTl2F6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. V4+ is bonded to six equivalent F1- atoms to form VF6 octahedra that share faces with eight equivalent TlF12 cuboctahedra. All V–F bond lengths are 1.88 Å. Tl1+ is bonded to twelve equivalent F1- atoms to form TlF12 cuboctahedra that share corners with twelve equivalent TlF12 cuboctahedra, faces with six equivalent TlF12 cuboctahedra, and faces with four equivalent VF6 octahedra. All Tl–F bond lengths are 3.07 Å. F1- is bonded in a single-bond geometry to one V4+ and four equivalent Tl1+ atoms.
