Materials Data on VPt by Materials Project

Abstract

PtV is Tetraauricupride structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. V2+ is bonded to eight equivalent Pt2- atoms to form distorted VPt8 hexagonal bipyramids that share corners with sixteen equivalent PtV8Pt4 cuboctahedra, corners with eight equivalent VPt8 hexagonal bipyramids, edges with eight equivalent PtV8Pt4 cuboctahedra, edges with twelve equivalent VPt8 hexagonal bipyramids, and faces with six equivalent VPt8 hexagonal bipyramids. All V–Pt bond lengths are 2.74 Å. Pt2- is bonded to eight equivalent V2+ and four equivalent Pt2- atoms to form distorted PtV8Pt4 cuboctahedra that share corners with twelve equivalent PtV8Pt4 cuboctahedra, corners with sixteen equivalent VPt8 hexagonal bipyramids, edges with eight equivalent PtV8Pt4 cuboctahedra, edges with eight equivalent VPt8 hexagonal bipyramids, and faces with ten equivalent PtV8Pt4 cuboctahedra. All Pt–Pt bond lengths are 2.70 Å.
