Materials Data on Na3TlF6 by Materials Project
Na3TlF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to twelve equivalent F1- atoms to form NaF12 cuboctahedra that share corners with twelve equivalent NaF12 cuboctahedra, faces with six equivalent NaF12 cuboctahedra, faces with four equivalent NaF6 octahedra, and faces with four equivalent TlF6 octahedra. All Na–F bond lengths are 3.09 Å. In the second Na1+ site, Na1+ is bonded to six equivalent F1- atoms to form NaF6 octahedra that share corners with six equivalent TlF6 octahedra and faces with eight equivalent NaF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Na–F bond lengths are 2.20 Å. Tl3+ is bonded to six equivalent F1- atoms to form TlF6 octahedra that share corners with six equivalent NaF6 octahedra and faces with eight equivalent NaF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Tl–F bond lengths are 2.17 Å. F1- is bonded in a linear geometry to five Na1+ and one Tl3+ atom.
