The compound described by Pt3Pb 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 Pb(1) atoms to form PtPt8Pb4 cuboctahedra that share corners with twelve equivalent Pt(1)Pt8Pb4 cuboctahedra, edges with eight equivalent Pb(1)Pt12 cuboctahedra, edges with sixteen equivalent Pt(1)Pt8Pb4 cuboctahedra, faces with four equivalent Pb(1)Pt12 cuboctahedra, and faces with fourteen equivalent Pt(1)Pt8Pb4 cuboctahedra. Pb(1) is bonded to twelve equivalent Pt(1) atoms to form PbPt12 cuboctahedra that share corners with twelve equivalent Pb(1)Pt12 cuboctahedra, edges with twenty-four equivalent Pt(1)Pt8Pb4 cuboctahedra, faces with six equivalent Pb(1)Pt12 cuboctahedra, and faces with twelve equivalent Pt(1)Pt8Pb4 cuboctahedra. is represented by the CIF card [CIF]
