Materials Data on CuPb3 by Materials Project

Abstract

CuPb3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Cu is bonded to twelve equivalent Pb atoms to form CuPb12 cuboctahedra that share corners with twelve equivalent CuPb12 cuboctahedra, edges with twenty-four equivalent PbCu4Pb8 cuboctahedra, faces with six equivalent CuPb12 cuboctahedra, and faces with twelve equivalent PbCu4Pb8 cuboctahedra. All Cu–Pb bond lengths are 3.37 Å. Pb is bonded to four equivalent Cu and eight equivalent Pb atoms to form distorted PbCu4Pb8 cuboctahedra that share corners with twelve equivalent PbCu4Pb8 cuboctahedra, edges with eight equivalent CuPb12 cuboctahedra, edges with sixteen equivalent PbCu4Pb8 cuboctahedra, faces with four equivalent CuPb12 cuboctahedra, and faces with fourteen equivalent PbCu4Pb8 cuboctahedra. All Pb–Pb bond lengths are 3.37 Å.
