Materials Data on GaPt3 by Materials Project

Abstract

Pt3Ga 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 Ga2+ atoms to form distorted PtGa4Pt8 cuboctahedra that share corners with twelve equivalent PtGa4Pt8 cuboctahedra, edges with eight equivalent GaPt12 cuboctahedra, edges with sixteen equivalent PtGa4Pt8 cuboctahedra, faces with four equivalent GaPt12 cuboctahedra, and faces with fourteen equivalent PtGa4Pt8 cuboctahedra. All Pt–Pt bond lengths are 2.79 Å. All Pt–Ga bond lengths are 2.79 Å. Ga2+ is bonded to twelve equivalent Pt+0.67- atoms to form GaPt12 cuboctahedra that share corners with twelve equivalent GaPt12 cuboctahedra, edges with twenty-four equivalent PtGa4Pt8 cuboctahedra, faces with six equivalent GaPt12 cuboctahedra, and faces with twelve equivalent PtGa4Pt8 cuboctahedra.
