Materials Data on ZnCrF6 by Materials Project
CrZnF6 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 ZnF6 octahedra. The corner-sharing octahedral tilt angles are 33°. All Cr–F bond lengths are 1.86 Å. Zn2+ is bonded to six equivalent F1- atoms to form ZnF6 octahedra that share corners with six equivalent CrF6 octahedra. The corner-sharing octahedral tilt angles are 33°. All Zn–F bond lengths are 2.05 Å. F1- is bonded in a bent 150 degrees geometry to one Cr4+ and one Zn2+ atom.
