Materials Data on ThSnPt by Materials Project
ThPtSn is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Th is bonded to four equivalent Pt and six equivalent Sn atoms to form a mixture of distorted face and corner-sharing ThSn6Pt4 tetrahedra. All Th–Pt bond lengths are 2.95 Å. All Th–Sn bond lengths are 3.41 Å. Pt is bonded in a body-centered cubic geometry to four equivalent Th and four equivalent Sn atoms. All Pt–Sn bond lengths are 2.95 Å. Sn is bonded in a 10-coordinate geometry to six equivalent Th and four equivalent Pt atoms.
