Materials Data on MnSnPt by Materials Project

PtMnSn is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Mn is bonded to four equivalent Pt and six equivalent Sn atoms to form a mixture of distorted corner and face-sharing MnSn6Pt4 tetrahedra. All Mn–Pt bond lengths are 2.69 Å. All Mn–Sn bond lengths are 3.11 Å. Pt is bonded in a body-centered cubic geometry to four equivalent Mn and four equivalent Sn atoms. All Pt–Sn bond lengths are 2.69 Å. Sn is bonded in a 4-coordinate geometry to six equivalent Mn and four equivalent Pt atoms.
