Title: Materials Data on K3WF6 by Materials Project

Abstract

K3WF6 is (Cubic) Perovskite-like structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded to twelve equivalent F1- atoms to form KF12 cuboctahedra that share corners with twelve equivalent KF12 cuboctahedra, faces with six equivalent KF12 cuboctahedra, faces with four equivalent KF6 octahedra, and faces with four equivalent WF6 octahedra. All K–F bond lengths are 3.27 Å. In the second K1+ site, K1+ is bonded to six equivalent F1- atoms to form KF6 octahedra that share corners with six equivalent WF6 octahedra and faces with eight equivalent KF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All K–F bond lengths are 2.51 Å. W3+ is bonded to six equivalent F1- atoms to form WF6 octahedra that share corners with six equivalent KF6 octahedra and faces with eight equivalent KF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All W–F bond lengths are 2.11 Å. F1- is bonded in a distorted linear geometry to five K1+ and one W3+ atom.
