Materials Data on ScSbPt by Materials Project
ScPtSb is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Sc3+ is bonded to four equivalent Pt2- and six equivalent Sb1- atoms to form a mixture of distorted face and corner-sharing ScSb6Pt4 tetrahedra. All Sc–Pt bond lengths are 2.77 Å. All Sc–Sb bond lengths are 3.20 Å. Pt2- is bonded in a body-centered cubic geometry to four equivalent Sc3+ and four equivalent Sb1- atoms. All Pt–Sb bond lengths are 2.77 Å. Sb1- is bonded in a 10-coordinate geometry to six equivalent Sc3+ and four equivalent Pt2- atoms.
