Title: Materials Data on K2NaAuBr6 by Materials Project

Abstract

K2NaAuBr6 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 Br1- atoms to form KBr12 cuboctahedra that share corners with twelve equivalent KBr12 cuboctahedra, faces with six equivalent KBr12 cuboctahedra, faces with four equivalent NaBr6 octahedra, and faces with four equivalent AuBr6 octahedra. All K–Br bond lengths are 3.91 Å. Na1+ is bonded to six equivalent Br1- atoms to form NaBr6 octahedra that share corners with six equivalent AuBr6 octahedra and faces with eight equivalent KBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Na–Br bond lengths are 2.87 Å. Au3+ is bonded to six equivalent Br1- atoms to form AuBr6 octahedra that share corners with six equivalent NaBr6 octahedra and faces with eight equivalent KBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Au–Br bond lengths are 2.66 Å. Br1- is bonded in a 2-coordinate geometry to four equivalent K1+, one Na1+, and one Au3+ atom.
