Materials Data on K3Sb2Au3 by Materials Project

Abstract

K3Au3Sb2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 6-coordinate geometry to six equivalent Au1- atoms. All K–Au bond lengths are 4.07 Å. In the second K1+ site, K1+ is bonded in a 1-coordinate geometry to six equivalent Au1- and one Sb atom. All K–Au bond lengths are 3.64 Å. The K–Sb bond length is 3.52 Å. Au1- is bonded in a 2-coordinate geometry to six K1+ and two equivalent Sb atoms. Both Au–Sb bond lengths are 2.71 Å. Sb is bonded in a 7-coordinate geometry to one K1+ and three equivalent Au1- atoms.
