Materials Data on NaBiF6 by Materials Project
NaBiF6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Na1+ is bonded to six equivalent F1- atoms to form NaF6 octahedra that share corners with six equivalent BiF6 octahedra. The corner-sharing octahedral tilt angles are 41°. All Na–F bond lengths are 2.34 Å. Bi5+ is bonded to six equivalent F1- atoms to form BiF6 octahedra that share corners with six equivalent NaF6 octahedra. The corner-sharing octahedral tilt angles are 41°. All Bi–F bond lengths are 2.05 Å. F1- is bonded in a bent 150 degrees geometry to one Na1+ and one Bi5+ atom.
