The material described by Yb3Pb crystallizes in the hexagonal P6_3/mmc space group. Yb(1) is bonded in a distorted see-saw-like geometry to four equivalent Pb(1) atoms. Pb(1) is bonded to twelve equivalent Yb(1) atoms to form a mixture of face and corner-sharing PbYb12 cuboctahedra. is represented by the CIF file [CIF]
