The crystal structure described by CuPb3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Cu(1) is bonded to twelve equivalent Pb(1) atoms to form CuPb12 cuboctahedra that share corners with twelve equivalent Cu(1)Pb12 cuboctahedra, edges with twenty-four equivalent Pb(1)Cu4Pb8 cuboctahedra, faces with six equivalent Cu(1)Pb12 cuboctahedra, and faces with twelve equivalent Pb(1)Cu4Pb8 cuboctahedra. Pb(1) is bonded to four equivalent Cu(1) and eight equivalent Pb(1) atoms to form distorted PbCu4Pb8 cuboctahedra that share corners with twelve equivalent Pb(1)Cu4Pb8 cuboctahedra, edges with eight equivalent Cu(1)Pb12 cuboctahedra, edges with sixteen equivalent Pb(1)Cu4Pb8 cuboctahedra, faces with four equivalent Cu(1)Pb12 cuboctahedra, and faces with fourteen equivalent Pb(1)Cu4Pb8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
