Title: Materials Data on KAsF6 by Materials Project

Abstract

KAsF6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. K1+ is bonded to twelve equivalent F1- atoms to form KF12 cuboctahedra that share corners with six equivalent AsF6 octahedra, edges with six equivalent KF12 cuboctahedra, and faces with two equivalent AsF6 octahedra. The corner-sharing octahedral tilt angles are 33°. There are six shorter (2.96 Å) and six longer (3.03 Å) K–F bond lengths. As5+ is bonded to six equivalent F1- atoms to form AsF6 octahedra that share corners with six equivalent KF12 cuboctahedra and faces with two equivalent KF12 cuboctahedra. All As–F bond lengths are 1.78 Å. F1- is bonded in a distorted single-bond geometry to two equivalent K1+ and one As5+ atom.
