PtCu3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pt(1) is bonded to twelve equivalent Cu(1) atoms to form PtCu12 cuboctahedra that share corners with twelve equivalent Pt(1)Cu12 cuboctahedra, edges with twenty-four equivalent Cu(1)Cu8Pt4 cuboctahedra, faces with six equivalent Pt(1)Cu12 cuboctahedra, and faces with twelve equivalent Cu(1)Cu8Pt4 cuboctahedra. Cu(1) is bonded to four equivalent Pt(1) and eight equivalent Cu(1) atoms to form CuCu8Pt4 cuboctahedra that share corners with twelve equivalent Cu(1)Cu8Pt4 cuboctahedra, edges with eight equivalent Pt(1)Cu12 cuboctahedra, edges with sixteen equivalent Cu(1)Cu8Pt4 cuboctahedra, faces with four equivalent Pt(1)Cu12 cuboctahedra, and faces with fourteen equivalent Cu(1)Cu8Pt4 cuboctahedra.
