Materials Data on CrNiF6 by Materials Project
CrNiF6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Cr4+ is bonded to six equivalent F1- atoms to form CrF6 octahedra that share corners with six equivalent NiF6 octahedra. The corner-sharing octahedral tilt angles are 34°. All Cr–F bond lengths are 1.86 Å. Ni2+ is bonded to six equivalent F1- atoms to form NiF6 octahedra that share corners with six equivalent CrF6 octahedra. The corner-sharing octahedral tilt angles are 34°. All Ni–F bond lengths are 2.02 Å. F1- is bonded in a bent 150 degrees geometry to one Cr4+ and one Ni2+ atom.
