Materials Data on VSiPt by Materials Project
VPtSi is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. V2+ is bonded in a 4-coordinate geometry to four equivalent Pt2+ and six equivalent Si4- atoms. All V–Pt bond lengths are 2.52 Å. All V–Si bond lengths are 2.91 Å. Pt2+ is bonded in a body-centered cubic geometry to four equivalent V2+ and four equivalent Si4- atoms. All Pt–Si bond lengths are 2.52 Å. Si4- is bonded to six equivalent V2+ and four equivalent Pt2+ atoms to form a mixture of distorted face and corner-sharing SiV6Pt4 tetrahedra.
