Materials Data on K2InAuF6 by Materials Project

Abstract

K2AuInF6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. 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 AuF6 octahedra, and faces with four equivalent InF6 octahedra. All K–F bond lengths are 3.23 Å. Au1+ is bonded to six equivalent F1- atoms to form AuF6 octahedra that share corners with six equivalent InF6 octahedra and faces with eight equivalent KF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Au–F bond lengths are 2.45 Å. In3+ is bonded to six equivalent F1- atoms to form InF6 octahedra that share corners with six equivalent AuF6 octahedra and faces with eight equivalent KF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All In–F bond lengths are 2.10 Å. F1- is bonded in a 6-coordinate geometry to four equivalent K1+, one Au1+, and one In3+ atom.
