CdPb3 is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. Cd(1) is bonded to four equivalent Pb(2) and eight equivalent Pb(1) atoms to form CdPb12 cuboctahedra that share corners with four equivalent Cd(1)Pb12 cuboctahedra, edges with eight equivalent Cd(1)Pb12 cuboctahedra, edges with sixteen equivalent Pb(1)Cd4Pb8 cuboctahedra, faces with four equivalent Cd(1)Pb12 cuboctahedra, and faces with eight equivalent Pb(1)Cd4Pb8 cuboctahedra. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded to four equivalent Cd(1), four equivalent Pb(1), and four equivalent Pb(2) atoms to form distorted PbCd4Pb8 cuboctahedra that share corners with twelve equivalent Pb(1)Cd4Pb8 cuboctahedra, edges with eight equivalent Cd(1)Pb12 cuboctahedra, edges with eight equivalent Pb(1)Cd4Pb8 cuboctahedra, faces with four equivalent Cd(1)Pb12 cuboctahedra, and faces with ten equivalent Pb(1)Cd4Pb8 cuboctahedra. In the second Pb site, Pb(2) is bonded in a distorted square co-planar geometry to four equivalent Cd(1) and eight equivalent Pb(1) atoms.
