Materials Data on KSb by Materials Project

Abstract

KSb crystallizes in the monoclinic P2_1/c 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 Sb1- atoms. There are a spread of K–Sb bond distances ranging from 3.58–3.76 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six Sb1- atoms. There are a spread of K–Sb bond distances ranging from 3.61–3.94 Å. There are two inequivalent Sb1- sites. In the first Sb1- site, Sb1- is bonded in a 8-coordinate geometry to six K1+ and two equivalent Sb1- atoms. There are one shorter (2.88 Å) and one longer (2.91 Å) Sb–Sb bond lengths. In the second Sb1- site, Sb1- is bonded in a 8-coordinate geometry to six K1+ and two equivalent Sb1- atoms.
