Materials Data on AcSnHg2 by Materials Project
AcHg2Sn is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ac is bonded in a distorted body-centered cubic geometry to eight equivalent Hg and six equivalent Sn atoms. All Ac–Hg bond lengths are 3.34 Å. All Ac–Sn bond lengths are 3.86 Å. Hg is bonded in a distorted body-centered cubic geometry to four equivalent Ac and four equivalent Sn atoms. All Hg–Sn bond lengths are 3.34 Å. Sn is bonded in a 8-coordinate geometry to six equivalent Ac and eight equivalent Hg atoms.
