Materials Data on CaWF6 by Materials Project
CaWF6 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 WF6 octahedra. The corner-sharing octahedral tilt angles are 29°. All Ca–F bond lengths are 2.28 Å. W4+ is bonded to six equivalent F1- atoms to form WF6 octahedra that share corners with six equivalent CaF6 octahedra. The corner-sharing octahedral tilt angles are 29°. All W–F bond lengths are 2.02 Å. F1- is bonded in a bent 150 degrees geometry to one Ca2+ and one W4+ atom.
