Materials Data on K5Sb4 by Materials Project

K5Sb4 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 7-coordinate geometry to seven Sb+1.25- atoms. There are five shorter (3.70 Å) and two longer (3.78 Å) K–Sb bond lengths. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six Sb+1.25- atoms. There are a spread of K–Sb bond distances ranging from 3.72–3.83 Å. In the third K1+ site, K1+ is bonded in a square co-planar geometry to four equivalent Sb+1.25- atoms. All K–Sb bond lengths are 3.58 Å. There are two inequivalent Sb+1.25- sites. In the first Sb+1.25- site, Sb+1.25- is bonded in a 9-coordinate geometry to eight K1+ and one Sb+1.25- atom. The Sb–Sb bond length is 2.83 Å. In the second Sb+1.25- site, Sb+1.25- is bonded in a 9-coordinate geometry to seven K1+ and two Sb+1.25- atoms. The Sb–Sb bond length is 2.87 Å.
