Materials Data on CsK3 by Materials Project
CsK3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Cs is bonded in a body-centered cubic geometry to eight equivalent K atoms. All Cs–K bond lengths are 4.77 Å. There are two inequivalent K sites. In the first K site, K is bonded in a distorted body-centered cubic geometry to four equivalent Cs and four equivalent K atoms. All K–K bond lengths are 4.77 Å. In the second K site, K is bonded in a body-centered cubic geometry to eight equivalent K atoms.
