The compound described by Pt3Al 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 Al(1) atoms to form distorted PtAl4Pt8 cuboctahedra that share corners with twelve equivalent Pt(1)Al4Pt8 cuboctahedra, edges with eight equivalent Al(1)Pt12 cuboctahedra, edges with sixteen equivalent Pt(1)Al4Pt8 cuboctahedra, faces with four equivalent Al(1)Pt12 cuboctahedra, and faces with fourteen equivalent Pt(1)Al4Pt8 cuboctahedra. Al(1) is bonded to twelve equivalent Pt(1) atoms to form AlPt12 cuboctahedra that share corners with twelve equivalent Al(1)Pt12 cuboctahedra, edges with twenty-four equivalent Pt(1)Al4Pt8 cuboctahedra, faces with six equivalent Al(1)Pt12 cuboctahedra, and faces with twelve equivalent Pt(1)Al4Pt8 cuboctahedra. is represented by the CIF card [CIF]
