Hg3Sb is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a body-centered cubic geometry to four equivalent Hg(2) and four equivalent Sb(1) atoms. In the second Hg site, Hg(2) is bonded in a body-centered cubic geometry to eight equivalent Hg(1) atoms. Sb(1) is bonded in a body-centered cubic geometry to eight equivalent Hg(1) atoms.
