Materials Data on K3Hg by Materials Project
K3Hg is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent K sites. In the first K site, K is bonded in a 4-coordinate geometry to four equivalent K and four equivalent Hg atoms. All K–K bond lengths are 4.05 Å. All K–Hg bond lengths are 4.05 Å. In the second K site, K is bonded in a body-centered cubic geometry to eight equivalent K atoms. Hg is bonded in a body-centered cubic geometry to eight equivalent K atoms.
