The compound described by K8Sb2Te crystallizes in the tetragonal I-4m2 space group. K(1) is bonded in a trigonal non-coplanar geometry to one Sb(1), one Sb(2), and one Te(1) atom. There are four inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a body-centered cubic geometry to eight equivalent K(1) atoms. In the second Sb site, Sb(2) is bonded in a body-centered cubic geometry to eight equivalent K(1) atoms. In the third Sb site, Sb(1) is bonded in a body-centered cubic geometry to eight equivalent K(1) atoms. In the fourth Sb site, Sb(2) is bonded in a body-centered cubic geometry to eight equivalent K(1) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a body-centered cubic geometry to eight equivalent K(1) atoms. In the second Te site, Te(1) is bonded in a body-centered cubic geometry to eight equivalent K(1) atoms. is represented by the CIF file [CIF]
