Materials Data on KSb3 by Materials Project
KSb3 is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. K1+ is bonded in a 11-coordinate geometry to eleven Sb+0.33- atoms. There are a spread of K–Sb bond distances ranging from 3.19–3.52 Å. There are two inequivalent Sb+0.33- sites. In the first Sb+0.33- site, Sb+0.33- is bonded in a 1-coordinate geometry to four equivalent K1+ and one Sb+0.33- atom. The Sb–Sb bond length is 2.97 Å. In the second Sb+0.33- site, Sb+0.33- is bonded in a trigonal planar geometry to three equivalent K1+ atoms.
