Materials Data on Cs2NaAlF6 by Materials Project
Cs2NaAlF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Cs1+ is bonded to twelve equivalent F1- atoms to form CsF12 cuboctahedra that share corners with twelve equivalent CsF12 cuboctahedra, faces with six equivalent CsF12 cuboctahedra, faces with four equivalent NaF6 octahedra, and faces with four equivalent AlF6 octahedra. All Cs–F bond lengths are 3.11 Å. Na1+ is bonded to six equivalent F1- atoms to form NaF6 octahedra that share corners with six equivalent AlF6 octahedra and faces with eight equivalent CsF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Na–F bond lengths are 2.51 Å. Al3+ is bonded to six equivalent F1- atoms to form AlF6 octahedra that share corners with six equivalent NaF6 octahedra and faces with eight equivalent CsF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Al–F bond lengths are 1.86 Å. F1- is bonded in a 2-coordinate geometry to four equivalent Cs1+, one Na1+, and one Al3+ atom.
