Pt3Bi is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pt(1) is bonded to eight equivalent Pt(1) and four equivalent Bi(1) atoms to form PtBi4Pt8 cuboctahedra that share corners with twelve equivalent Pt(1)Bi4Pt8 cuboctahedra, edges with eight equivalent Bi(1)Pt12 cuboctahedra, edges with sixteen equivalent Pt(1)Bi4Pt8 cuboctahedra, faces with four equivalent Bi(1)Pt12 cuboctahedra, and faces with fourteen equivalent Pt(1)Bi4Pt8 cuboctahedra. Bi(1) is bonded to twelve equivalent Pt(1) atoms to form BiPt12 cuboctahedra that share corners with twelve equivalent Bi(1)Pt12 cuboctahedra, edges with twenty-four equivalent Pt(1)Bi4Pt8 cuboctahedra, faces with six equivalent Bi(1)Pt12 cuboctahedra, and faces with twelve equivalent Pt(1)Bi4Pt8 cuboctahedra.
