Materials Data on K8In11 by Materials Project
K8In11 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. there are two inequivalent K sites. In the first K site, K is bonded in a 3-coordinate geometry to nine In atoms. There are a spread of K–In bond distances ranging from 3.81–4.15 Å. In the second K site, K is bonded in a 7-coordinate geometry to seven In atoms. There are a spread of K–In bond distances ranging from 3.65–4.02 Å. There are three inequivalent In sites. In the first In site, In is bonded in a 2-coordinate geometry to four K and six In atoms. There are a spread of In–In bond distances ranging from 3.01–3.33 Å. In the second In site, In is bonded in a 10-coordinate geometry to six K and four In atoms. There are one shorter (3.10 Å) and one longer (3.15 Å) In–In bond lengths. In the third In site, In is bonded in a 12-coordinate geometry to six equivalent K and six In atoms.
