The structure described by K8SnSb4 crystallizes in the cubic Fd-3m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to two equivalent Sn(1) and six equivalent Sb(1) atoms. In the second K site, K(2) is bonded in a 4-coordinate geometry to four equivalent Sb(1) atoms. Sn(1) is bonded in a body-centered cubic geometry to four equivalent K(1) and four equivalent Sb(1) atoms. Sb(1) is bonded in a 10-coordinate geometry to three equivalent K(1), six equivalent K(2), and one Sn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
