Materials Data on SnPt3 by Materials Project
Pt3Sn is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Pt+0.67- is bonded to eight equivalent Pt+0.67- and four equivalent Sn2+ atoms to form PtSn4Pt8 cuboctahedra that share corners with twelve equivalent PtSn4Pt8 cuboctahedra, edges with eight equivalent SnPt12 cuboctahedra, edges with sixteen equivalent PtSn4Pt8 cuboctahedra, faces with four equivalent SnPt12 cuboctahedra, and faces with fourteen equivalent PtSn4Pt8 cuboctahedra. All Pt–Pt bond lengths are 2.87 Å. All Pt–Sn bond lengths are 2.87 Å. Sn2+ is bonded to twelve equivalent Pt+0.67- atoms to form SnPt12 cuboctahedra that share corners with twelve equivalent SnPt12 cuboctahedra, edges with twenty-four equivalent PtSn4Pt8 cuboctahedra, faces with six equivalent SnPt12 cuboctahedra, and faces with twelve equivalent PtSn4Pt8 cuboctahedra.
