Materials Data on PuHg3 by Materials Project
PuHg3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Pu is bonded in a distorted body-centered cubic geometry to fourteen Hg atoms. There are eight shorter (3.19 Å) and six longer (3.68 Å) Pu–Hg bond lengths. There are two inequivalent Hg sites. In the first Hg site, Hg is bonded in a distorted body-centered cubic geometry to four equivalent Pu and four equivalent Hg atoms. All Hg–Hg bond lengths are 3.19 Å. In the second Hg site, Hg is bonded in a 8-coordinate geometry to six equivalent Pu and eight equivalent Hg atoms.
