Cd3Pb is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. There are three inequivalent Cd sites. In the first Cd site, Cd(1) is bonded to eight Cd(1,1) and four equivalent Pb(1) atoms to form distorted CdCd8Pb4 cuboctahedra that share corners with four equivalent Pb(1)Cd12 cuboctahedra; corners with fourteen Cd(1,1,1)Cd8Pb4 cuboctahedra; edges with six equivalent Pb(1)Cd12 cuboctahedra; edges with twelve Cd(1,1)Cd8Pb4 cuboctahedra; faces with four equivalent Pb(1)Cd12 cuboctahedra; and faces with sixteen Cd(1,1,1)Cd8Pb4 cuboctahedra. In the second Cd site, Cd(1) is bonded to eight Cd(1,1,1) and four equivalent Pb(1) atoms to form distorted CdCd8Pb4 cuboctahedra that share corners with four equivalent Pb(1)Cd12 cuboctahedra; corners with fourteen Cd(1,1,1)Cd8Pb4 cuboctahedra; edges with six equivalent Pb(1)Cd12 cuboctahedra; edges with twelve Cd(1,1,1)Cd8Pb4 cuboctahedra; faces with four equivalent Pb(1)Cd12 cuboctahedra; and faces with sixteen Cd(1,1,1)Cd8Pb4 cuboctahedra. In the third Cd site, Cd(1) is bonded to eight Cd(1,1) and four equivalent Pb(1) atoms to form distorted CdCd8Pb4 cuboctahedra that share corners with four equivalent Pb(1)Cd12 cuboctahedra; corners with fourteen Cd(1,1,1)Cd8Pb4 cuboctahedra; edges with six equivalent Pb(1)Cd12 cuboctahedra; edges with twelve Cd(1,1)Cd8Pb4 cuboctahedra; faces with four equivalent Pb(1)Cd12 cuboctahedra; and faces with sixteen Cd(1,1,1)Cd8Pb4 cuboctahedra. Pb(1) is bonded to twelve Cd(1,1,1) atoms to form PbCd12 cuboctahedra that share corners with six equivalent Pb(1)Cd12 cuboctahedra; corners with twelve Cd(1,1)Cd8Pb4 cuboctahedra; edges with eighteen Cd(1,1,1)Cd8Pb4 cuboctahedra; faces with eight equivalent Pb(1)Cd12 cuboctahedra; and faces with twelve Cd(1,1,1)Cd8Pb4 cuboctahedra.
