Materials Data on CaNiF6 by Materials Project
CaNiF6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Ca2+ is bonded to six equivalent F1- atoms to form CaF6 octahedra that share corners with six equivalent NiF6 octahedra. The corner-sharing octahedral tilt angles are 29°. All Ca–F bond lengths are 2.28 Å. Ni4+ is bonded to six equivalent F1- atoms to form NiF6 octahedra that share corners with six equivalent CaF6 octahedra. The corner-sharing octahedral tilt angles are 29°. All Ni–F bond lengths are 1.80 Å. F1- is bonded in a bent 150 degrees geometry to one Ca2+ and one Ni4+ atom.
