Materials Data on ErSbPt by Materials Project
ErPtSb is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Er3+ is bonded to four equivalent Pt2- and six equivalent Sb1- atoms to form a mixture of distorted face and corner-sharing ErSb6Pt4 tetrahedra. All Er–Pt bond lengths are 2.85 Å. All Er–Sb bond lengths are 3.29 Å. Pt2- is bonded in a body-centered cubic geometry to four equivalent Er3+ and four equivalent Sb1- atoms. All Pt–Sb bond lengths are 2.85 Å. Sb1- is bonded in a 10-coordinate geometry to six equivalent Er3+ and four equivalent Pt2- atoms.
